How much bitcoin could have have mined back in 2014 with a Radeon 7970 3GB?

I used to have a PC with a Radeon 7970 3GB OC version sitting idle in a air conditioned room back in 2014. I never thought about putting it to work back then.
I am wondering how much bitcoin I could have mined with this card between 2014 until 2016 if I had it run 24/7?

Back to the Future: 2014 Bitcoin increase, market Crash, and GPUs flood the market.

Image a world, where Bitcoin hits a new ATH of 1,000 USD! A new coin emerged, Litecoin. Using a new Algorithm called SCRYPT which makes GPU mining profitable and a thing again!
The story starts in January 2014. AMD Just released it's newest GPU, the R9 290X in late Oct. this thing a monster of a GPU, extremely powerful! A GPU mining crazy has just hit the internet and waves of Tech people are making mining farms to mine Crypto. AMD GPU's are priced at premiums with 290's/290x's OOS or for sale upwards of $700, $200 over MSRP. Everyone is gulping up used AMD GPUs. Ebay is awash with GPUs selling over MRSP even used ones!
I was there, I started out mining Litecoin to Litecoinpool.org, I had 3 Rigs I slapped together in crate boxes. Mixature of 7970/7950/7850's and a single a 4 GPU R9 290x rig (over 1400w!!!) using AMD AM3+ Motherboards and CPU's running Windows 8. I even near the end had a 750ti Rig, the new Maxwell, efficiently mining SRCYPT. I'm glad i lived in WA at the time The electric bill wasn't bad at all maybe 200-300 a month. I lived in Ellensburg getting that sweet Wind farm Electric rate. I Remember this time as I struggling to learn mining, overclockings for mining, and rig stability. In the short period I did this February 2014 to May of 2014 I made 48 Litecoins. This was a fun period for me because I loved messing with the hardware and GPUs even made decent profits from selling used hardware because it became such a premium then. In the end I quit mining and sold all my hard around May/June. Then moved back to CA to live with my mom to help support her after she lost her job and couldn't find work. I sold off my entire small operation. In the end the Market crashed, MT GOX was hacked millions of Bitcoin lost, and SCRYPT ASICs were released. I stopped paying much attention to the crypto-sphere and just HODLed the small Bitcoin that I had traded from the Litecoin I earned. Bitcoin dropped down to $200 by the end of that year.
All in all I just want everyone to take in the fact that this exact, I repeat EXACT, thing has happened before in the long forgotten past of 2014. Yet everyone is making it out like its some crazy big deal? every crypto is still at high comparing to previous years, GPUs have declined in price because mining has died down, and ASICs are coming out for almost every Algo.
To those of you still mining, keep on my brother! If I had kept mining, or kept on eye on the crypto sphere rather than walking away like most are right now, I could mined Etherum back in the early days of 2015 and now could of been extremely well off. Now, that im in it again and this time with more foresight and readiness. I'm here to stay through this rough times. hopefully to come out to see the otherside. I Only started(again) in june 2017 so I was late for this "gold rush" but mark my words the massive "Gold rush" for crypto has yet to come...

[Discussion] My own personal guide to used hardware alternatives.

Hi there. My name is Jeff. I've been building systems for the better part of 15 years and try my best to contribute here actively. After being involved in this little community for a few years now, I'm noticing a serious lack of discussion about buying used components, and I feel like it's time to shed a little light on the subject for those looking to build on a (seriously) tight budget.
As Linus said in his scrapyard wars video, buying new on $300 isn't practical, and if you posed the challenge to him on a random day, buying used is almost certainly the path he'd choose. As someone who's been "scrapyarding" as a hobby for the better part of 10 years, I figured I'd take some time to share some of what I've learned for the modern audience.
Let's begin with a simple rundown of modern "budget" choices, and I'll tell you what I'd do instead.
CPU
The G3258 and Athlon 860k are the sub-$100 CPUs of choice, and both work just fine. I have built with both in the past, and each carries their own set of advantages.
Used Alternatives: You can go in a couple of directions here; if you happen to have an LGA 1366 motherboard lying around, you can get an i7 920 or better for under $50, and they still hold up reasonably well. Being that LGA 1366 boards are not typically cheap when purchased used, my favourite option is the Phenom II x4 Black Edition series, each of which compare favourably to modern budget options, and will even overclock on some incredibly dated, dirt cheap AM2+ boards. In my experience, eBay prices on these get a little too high for my taste, but I've been able to nab several on Kijiji locally in Toronto for under $50 as well.
GPU
The R7 260x and GTX 750 ti are often cited as budget options for most builders, with the latter serving a very specific role in systems where power draw might be a concern. While there exists no option that can complete with the low consumption of the 750 ti (or even the single 6-pin connector goodness of the 260x), its performance can easily be matched (and exceeded) for less money.
Used Alternatives: The bitcoin mining craze from a few years back led to the Radeon 7950 and 7970 being blacklisted on the used market, and I think the fears about burned-out cards are a little overblown. Here in Toronto, you can easily grab a 7950 for the price of a 260x, but I don't pay anywhere near that for my builds. At most, a Windforce will cost me $125, as where I recently picked up some non-boost edition PowerColor versions for a mere $83 each (bought 3 for $250).
EDIT: Forgot to mention something important - avoid the reference 7950 and 7970. They were employed to a far greater degree in mining rigs because of their rear-only exhaust, and if you see a bunch of them from the same seller listed at once, they're likely old mining cards. Only pick them up if they're incredibly cheap.
Want to go even cheaper? The Radeon 6950 (with the shader unlock, preferably) or even the 6970 will rival the performance of the 260x, and shouldn't cost Canadians more than $50-$60. I personally have 2 in my possession right now, and have gone through at least a dozen in the last 6 months.
In general, one should always avoid Nvidia when buying used, because they are far too popular and overvalued for their performance as they age. I still see GTX 660s selling for $150, which is absolutely absurd.
Motherboards
Motherboards on the used market are weird, and this can largely be attributed to the fact that they're hard to transport and don't handle well over time. As such, people don't really sell boards on their own that often, and you'll likely have more luck finding a combo of some kind (or even a ready-to-go tin-can with no graphics card) for less per part than you will finding a given board on its own.
Used Alternatives: The boards I'd recommend depend entirely on the CPU you've chosen. Being that I'm a fan of the Phenom II x4 series, AM2+ boards are going to be dirt cheap, but DDR2 RAM is actually fucking expensive, so you'd likely be better off going with AM3. I've even seen some used AM3+ boards (The 970 ASRock Extreme3, in particular) for as low as $40, so it wouldn't hurt to look.
On the Intel side, you're actually at a significant disadvantage. Much like Nvidia cards, Intel boards (and CPUs) actually retain their value and don't often come cheap. For me, LGA 1156 is the price/performance sweet spot, granted I can find an i7 8XX to go with it. Even still, they're going to run you a fair bit more than an AMD board, and likely aren't worth it by comparison.
RAM
Ram is ram. DDR2 is pricy as fuck due to an obvious market shortage of the stuff, so the AM2+ board option might not be best by comparison. DDR3 ram, however, is ubiquitous, and I always die a little inside when people building on a "budget" choose to buy new at all. If I'm being honest, I can get DDR3 ram from e-waste recycling companies for as low as $10 per 4GB stick, at 1333MHz, and not once have I ever had a bad stick of the stuff. Even for people going the route of the G3258 (which only supports 1333MHz), this is the clear winner.
Is value RAM ugly as sin? Sure it is. It is just as good as that fancy Ripjaws shit you've got in your current build? You betcha.
Storage
Hard Drives are actually a tricky game, as they are the single most volatile component in any budget build, easily succumbing to wear and tear from age and daily use. As such (and some might find this hard to believe) I actively avoid HDDs when building value systems for people and opt for cheap SSDs instead. As always, check the date on a drive if you're really insistent on buying one, and considering how cheap a WD blue is new, don't pull the trigger on one unless it's for less than $30/TB.
SSDs are obviously (akin to RAM) highly resilient and are nearly guaranteed to work when purchased used. The average SSD pulled from an old laptop or an office off-lease desktop, will have no more than 100GB of writes on it, which leaves 99% of its life for you to exploit. While there exists no specific recommendation for which brand to buy, just be sure you're getting a relatively good drive with SATA III capability. 120/128GB variants of these sorts should cost you no more than $50 in my native Canada, and I've even gotten lucky on some larger sizes too. Recently I picked up 4 256GB Samsung 840 Pros for $75 each (I came), just days after I bought a Crucial MX100 of the same size for $85.
Monitors
Monitors are fun to buy, because the recent shifts in display technology have rendered a lot of recent-but-obsolete models nearly valueless. For example, remember when 16:10 was a thing? I actually still like 1680x1050 monitors, but the rest of the world seems to disagree, so I've been able to pick up 23" variants for as little as $40. Being that the slightly lower resolution actually eases the strain on your VRAM a bit, it's a nice fit for a lot of budget cards that might not have a full 2GB available, like some variants of the 6950. 1600x900 monitors are often just as cheap and come with the same inherent benefit of being obsolete despite being almost as good as its bigger 1080p cousin.
Keyboards and Mice
If you're on a budget, we can't even have this discussion. As much as I like mechanical keyboards and high-precision gaming mice, people building used $300 systems aren't going to allot any of their budget buying them. That said, wired USB keyboards and mice are virtually free (search your local goodwill or value village for some), and if you have to pay money, buy a wireless combo for $20 new from some little shit store in a suburb somewhere.
Cases
Cases on their own sell for about half of their original retail price, give or take based on the condition. I normally just get them as a part of a tin-can bundle and make use of them if they aren't too dirty, but when building for someone else, I'd often just prefer to buy a new budget case in the $40 range.
PSUs
I saved this topic for last, because it's by far the most difficult category to master. First off, you really need to do your research and understand how PSUs work before delving into these guys, as the cost associated is almost entirely dependent on how resilient the underlying platform has been proven to be. Generally speaking, reading reviews on JonnyGuru and HardOCP is a great start, but none of them account for units that are several years old.
As a general rule of thumb, I use the EVGA 500W W1 as a reference point, and build my value tree around that. In other words, if a new EVGA 500W (a passable, proven budget unit) is cheaper than a used 500W variant of a better brand, why would I bother buying used? Sure, that 520W Seasonic S12II puts the EVGA to shame in terms of voltage regulation and ripple suppression, but can I really make the same claims of a unit that's 5 years into its life? Wouldn't I just be safer buying new? These are all factors you have to consider.
For me, the threshold lies around 50% in terms of cost savings vs. risk. In other words, if you can find a used quality unit for less than half the price of the cheapest quality unit available at a given time, buy it.
Anyhow I think that covers everything. And as a closing note, remember to be safe. Meet potential sellers (and buyers) in public, well-lit places, and try your best to avoid entering someone's home without some protections in place. Also, the more info you get about the person (address, phone number, etc) the less likely it is that a person will be trying to scam you. People who purposely conceal their identity do so for a reason.
Also, feel free to ask me anything about my own experiences buying and selling used. I've been doing it as a hobby for a long, long time and have sold many value builds to people who can't otherwise afford PCs. I'm happy to impart any wisdom I might've gained over the years.
Edit: CPU Coolers! Forgot those. Air coolers are a safe bet. They're slabs of copper and aluminum with fans strapped to them. Buy with confidence, and seek one out for $10-$15 if you plan to overclock. AIO water cooling is not so safe. Those things are typically only good for 2-3 years, and you have no idea how much longer a pump has before it gives. Budget builders likely aren't water-cooling anyhow, right?
Edit 2: Just to be clear, when I said I'd been doing this for a long time, I should clarify that a) I once owned a game store and sold systems out of there and b) I currently resell systems out of my house to raise money for charity builds. I really don't want people to get the impression I'm trying to sell anything.

Of Wolves and Weasels - Day 259 - Guest Post: Clarifications and Thoughts on Dogeparty and the Community

Hey all, GoodShibe... on Vacation!
Today's Guest Post comes to us from pseudopseudonym and they've put a lot of work into it, so please lend them your ears [eyes?] ;D)
Disclosure statement: I am not a Dogeparty or Dogecoin developer. I am currently holding a total of 98.566 XDP and own 55 Dogeparty assets, none of which I have profited from (nor plan to profit from) in any way. I recently took on the role of Community Manager for Dogeparty, which is an unpaid position.
I have been involved in Dogecoin since the fairly early days and have always been proud to be part of this community, even in a small way. Like many of you I’ve seen us grow and blossom through various events, and recently shared in the pain of loss with you all. My experience with Dogecoin so far consisted of mining hundreds of thousands of Dogecoin with a Radeon 7970, purchasing an R9 280X and never getting to use it due to being hospitalized. In my entire time in the Dogecoin community, one of the most controversial things I witnessed was Dogeparty.
Many aspects of Dogeparty have created confusion. For the first week or so it was discussed on the subreddit, I viewed it as a weird distraction that I couldn’t properly understand. Over time various aspects of it became clear to me - Proof of Burn, what it was to be used for, the relationship (or lack thereof) that it had with Dogecoin and why Dogecoin was being used by the developers. If you’re currently confused, hopefully this post is for you!
Dogecoin and Dogeparty are both very new technologies and are somewhat experimental. Dogeparty builds on the Dogecoin blockchain and enables for the secure transmission of tokens and assets between users, as well as a lot of other cool stuff. Assets can be used for just about any purpose you can think of; and cost 0.5 XDP to produce. Just over a month ago, a “burn” period was started where people could send DOGE to a provably unspendable address in exchange for XDP. About 1.85 billion DOGE was exchanged for XDP over that burn period. You can read more about Dogeparty and what it does on the Dogeparty website - it does a better job of explaining it than I can.
Exchanging DOGE for XDP serves a single purpose: creating value for the XDP tokens. It is not intended as a way of reducing inflation for Dogecoin, nor is it a way of taking DOGE away from Dogecoin users. As a result of the burn, there is now plenty of XDP to go around, which will hopefully enable lots of innovative projects in the future. We’ve already seen a lot of interesting things going on in Counterparty - Storj, LTBcoin and Swarm just to name a few.
Lots of exciting things are happening with Dogeparty right now. With the burn over, the decentralized exchange in Dogeparty should be coming online soon, and many of the initial teething issues Dogeparty faced are over. There is still a lot of work to be done, and it’s early days for Dogeparty - if you want to help, feel free to join the Skype discussion, use Dogeparty and report bugs to the project on GitHub.
Recently a post was made by a prominent community member sharply criticizing Dogeparty in various ways. While the post was largely dismissed, it raised some points that need addressing.
We’re always seeking new developers and contributors. If you’re interested in helping out, we’d love to hear from you, especially if you know Python!
As ever, I’m excited to be on this rocket with you all, and I look forward to seeing everything the community can do. If you have any questions about Dogeparty or just want to chat, feel free to ask in the Skype chat or on IRC (I’m Gnomethrower on #dogecoin) or right here on Reddit. I’ll do my best to answer any questions you have, and relay anything I can’t to the Dogeparty team. I will leave you with this thought: “If we turn a blind eye to that which we do not know, we will never see past the horizon”.
With the amount of technologies and talent in the Dogecoin community, I can’t wait to see what we’ll do next. To the moon!
It's 8:03AM EST and we've found 92.97% of our first 100 Billion DOGEs - only 7.03% remains until we reach our soft cap! Our global hashrate is on the rise from ~744 to ~769 and our difficulty is up from ~7215 to ~9391.
As always, I appreciate your support!

Not So Brief History of my Radeon HD7950 ASUS Direct CU II

Sexy Beast Pic 1: https://i.imgur.com/dQC90.jpg
Sexy Beast Pic 2: http://www.legitreviews.com/images/reviews/1839/7970-dc2-top.jpg
ASUS HD7950 Direct CU II. This card mined 1.5-3 BTC Bitcoin for me. Started with Bitcoin, then mined Litecoin in the early days of Litecoin GPU mining. Had 2 X ASUS HD7950s running 24/7/365 at the time. Each did about 3 BTC each total, and then switched full time to LTC Litecoin. This card was also used for CS gaming, 3D rendering, real time graphics, some video editing, and yes, yes more mining! Still RUNNING today! AMD FTW!
After some test mining Litecoin for a month, I quickly built 2 more Radeon GPU rigs to mine LTC. Total 3 rigs 12 cards. Blazin! Then in Dec 2013 this setup mined millions of Dogecoin in a few days shortly after launch,... I remember raking in over 300-500K DOGE / day at full throttle. We setup our own Doge Pool, and DOGE miners were chatting on IRC: The Excitement was REAL!
This fun SUCH DOGE WOW time was cut short by a massive ice storm that knocked out the power for a week. So no more DOGE. When I got back online diff was up and production down to 30K per day or less, but DOGE price skyrocketed so I sold DOGE for a good profit.
I remember donating DOGE to send the Jamaican Bobsleigh Team to the 2014 Winter Olympics, and they made it to Sochi! What a time to be alive! I was a DOGE Millionaire by then... Such Card, Much DOGE! WOW!
Shortly after that, around March 2014 the second HD7950 blew some caps and need to be sent to ASUS for service. ASUS promptly replaced the card under 3 year warranty and shipped a replacement in two weeks. Mining frenzy continued with FeatherCoin and PotCoin. DGB Digibyte was the next chapter! ;]
In summer 2015 I decided to part with one of them. Sold on Kijiji to a local fellow gamer that had his video card blow up, and didn't have enough $ to buy a new one. Gave him a deal. The guy was so happy, it was like Xmas for him. I knew that this ASUS 7950 will have a great home. So I said Good Bye to engine #2.
When this card is retired I will box it for display. Been through so much with it, still my number 1 engine. When something is this good, you keep it in the Fam'. Still works great. Thank you ASUS & AMD for making kick ass products! Over & Out! Peace! ;]

Made $1 Million mining. Want to Cash out. worried about being unemployed

Basically back in early 2016, I bought some second hand Radeon 7970s and r9 280x and been mining ETH since it pretty much launched. Back then you basically made like 1 ETH per GPU per day. Back then a 280x mined at like 27MH/s since the DAG was very small. Even my R9 270X mined at like 20MH/s.
I kept all this ETH, along with the free ETC, sold all of my ETH/ETC when it peaked at $400 last Summer and went all in BTC. BTC went 5x since that time. Also got the free bitcoin forks.
I kept cashing out a small amount with bitcoin ATMs and basically quit my job since it wasn't worth the hassle.
Now I want to buy a house but I am worried about sending $1,000,000 to an exchange like Gemini/Coinbase/Kraken/Bitstamp and have them freeze this BTC.
I am worried they will ask for employment papers and I've been unemployed since 2016.
All this money was made legally. However since I mined to an exchange instead of my personal ETH wallet, I might not be able to provide a signed message proving I am the one who mined those coins. Since all the coins were mined directly to my Poloniex account. I do have receipts for some RX 470s that I bought last year and wondering if its sufficent. Do I need to take photos of my mining rigs and show it to my exchange as proof?
I know I can buy USDT tether but I am worried that its not really backed by anything. I also don't know if any of the Bitcoin Future Options will be sufficient since they might carry crazy premiums for the puts.
Wondering if people had issues withdrawing large amounts.

A disgruntled opinion/rant regarding Bitcoin/Litecoin/etc. mining and the enthusiast GPU market.

Back in June of 2012, I very eagerly built my rig with a single Radeon 7950 in anticipation of crossfiring it down the road with a 7970. Now that time has come, and in my efforts to procure what I had anticipated to be quite the bargain, I am absolutely flabbergasted by what I discovered.
There's not a decent Radeon 7xxx in sight, and the 7970s that I could find are going for upwards of $400 USD! This is simply unacceptable for a two-year-old card, and even more unacceptable when considering that these very cards were (according to this guide) retailing for $269.99 this past October! That is nearly a 50% price increase in just two months at the very end of the card's life, and just after the universal price drop to all 7xxx units complimenting Nvidias launch of their GTX700s.
I hope I'm not being oblivious/naive here - and please correct me if I am - but I have NEVER seen that happen before with ANY consumer product (that is being replaced by a new revision). Of course I know the economic rules of supply & demand: There are lots of people who want these few cards, so AMD can afford to boost the price on them. However, this is pretty unreasonable considering AMDs focus on the new R9 chips, which are the new supply.
The perpetrator here is the growing trend of Bitcoin mining. The computing power and efficiency of AMDs GCN architecture is extremely good at mining for this "magic internet money." A growing amount of people are noticing this, and thus demand for AMDs chips has blown up like crazy. It's even become a goddamn selling point in advertisements.
I understand that the processing power of these cards can be very well harnessed for coin mining, and that's fine. However, for those of us enthusiasts that enjoy using our video cards to push pixels, I anticipate this trend to continue putting a strain on the market and our wallets.
TL;DR: I'm butthurt about last-gen AMD GPU prices being unreasonably high, and get mad (within reason).
*edit: AMD is not boosting prices, retailers are. Thanks to Shrederrr for clarifying.
**edit: To all the people suggesting that I sell my 7950 on the secondhand market, thanks; that is a good idea. Honestly the solution didn't cross my mind at the time of making this post - I was still reeling from the unbelievable prices and frustrated that I wasn't able to follow my planned upgrade path. This unprecedented Bitcoin/Litecoin phenomenon caught me by surprise and it saddens me somewhat to see these enthusiast GPUs being used in such a menial, greedy fashion. It's like seeing a Ferrari V12 powering a backup generator for a t-shirt factory. Sure it's being put to good use, but it's just...not right.

Get my mining rig to boot, I'll pay you +$30 in bitcoin right now!

Whoever get's my mining rig to boot up and get mining properly, will be sent +$30 in bitcoin instantly from my coinbase account. I have bitcoin ready to be sent as soon as my system is up and running. Please take a look at the info below and reply with a solution! First person to fix my rig will be sent the bitcoin!
The setup:
MOBO: ASRock Fatal1ty Z87 Killer LGA 1150 Intel Z87 CPU:Intel Pentium G3220 Haswell 3.0GHz LGA 1150 PSUs: 2x EVGA SuperNOVA 1000 G2 80 PLUS GOLD Certified 1000W GPUs: 2x SAPPHIRE 11197-03-CPO Radeon HD 7970 3GB 3x GIGABYTE GV-R928XOC-3GD REV2 Radeon R9 280X 3GB Memory: 2x 4GB DDR3 1600mhz Corsair Vengence Other: 16x and 1x molex powered risers, add2psu adapter
I have three gigabyte windforce gpu's and two sapphire 7970 cards. For some reason I cannot get my rig to boot with 4 gpu's or more. I got my rig to boot into win8.1 a day ago with 4 gpu's but after restarting it, It refused to post again. I have risers on all the slots and have tried configurations with the gpu's in different slots. I have jumped the A1 and B17 pins on two of the 1x pci-e slots (last two 1x slots furthest from the cpu) and jumped the A1 and B81 pins on three 16x pci-e slots. I've tried configs with two 280x gpu's on 16x risers and with two 7970 gpu's on 1x risers. I've also tried three 280x gpu's on 16x risers and one 7970 gpu on a 1x riser. I've tried many similar configs but I have had little to no luck. Im using dual psu's with the add2psu adapter. They're the same evga 1000w psu's. All the risers are powered too. And I do receive 5 beeps as an error code through the mobo speaker when I try to boot sometimes. If not, the fans just get loud and the system never boots. All the graphics cards are plugged into the primary psu and so are all the molex cables powering the gpu risers. The second psu only has a single 24 pin cable being plugged into the add2psu adapter.
Working solutions will be rewarded! Thanks :D

[XFX 7970s] 1.345 MHash/sec, ~35C, ~450 Watts

Resurrected my old Bitcoin rig for some dedicated LTC mining, FINALLY got it running stable after some serious procrastination studying for finals -__-
Evidence!: http://imgur.com/a/K3nYt
GPUs: 2x XFX Radeon HD 7970 GHz Edition (FX797GTDFC) flashed with this Gigabyte BIOS - http://www.techpowerup.com/vgabios/127156/gigabytehd7970-3072-120905.html
cgminer config: http://pastebin.com/raw.php?i=s072rzFF
Don't listen to anyone who says XFX GPUs are junk; maybe their firmware is, I won't argue that... but using the Gigabyte BIOS above I was able raise my hash rate to ~700 on each card @ 1000/1375 using around 450 watts, vs. ~550 on each card @ 1200/1500 using around 650 watts on the stock firmware!

I took the plunge - 2x 7970's on their way for potential rig - I have no idea what I'm doing - Help appreciated!

So since this past Spring break, my brother in his all powerful insider knowledge on this strange thing named BitCoins introduced me to this bandwagon. I've since joined in and bought all I could muster with the funds in my bank without ruining myself and have thus far reaped a beautiful profit that my wife deems pleasant. This is, of course, something EXTRAORDINARY. Ahem. So I decided to wager my trust I've earned with her with said investment, and have decided to use a few more funds to build a mini miner. Obviously this won't be the mega tank that you see all over Youtube, Just a simple machine that may have the potential of 1.6GH/s is my hope.
So this is what I've bought so far:
Total thus far after Rebates & Selling Games: ~$1300 USD
Estimated 1.6GH/s with profits beginning in ~85 days (Before crash, of course XD - Now who knows!)
Great thing is if all this goes kaput, I'll at least be able to resell it all! :D
I have a monitor around for initial setup, and all the other obvious peripherals. What I am in need of are some tips or links in setting these 2 guys up. I'm somewhat new to Building a PCI-E Rig, but I'm sure its just as simple as plugging it all in, which I've done countless times before. I know that if I'm on Linux I won't need any dummy plugs for the DVI outputs on the other cards for it to be recognized by the OS. Can it be run purely all on a USB drive? That's one thing I'm a little unsure of.
Mostly my questions consist of:
I don't care much for people bantering about how difficult it is now to mine, or how ineffective this might be, I've read my share about that. I plan on just having this run in the corner of my little apartment for a few months while I go to school/work/walk the dog/etc... I would like tips or any insider info on other fellow 7970'ers on how to maximize my performance with these two cards at my disposal. And of course those who do help me in my time of need and once it's all beautiful and vampiric-sparkly like will get Brownie Points in the afterlife.
Last computer I built was back in 2004 so that I could play Half Life 2. And I was on a budget back then too. So I'm not too savvy with all this new cooling hardware and techniques as I've never had to deal with things that exceeded 4x AGP.
I'll post pictures and videos of all the fun I have with this adventure :D
Update
Thus far I have only received my two 7970's and boy do they look beastly. I've never held a card that manly before.
2nd Update
Everything came in! Goodness it's difficult to do a headless Linux Box! for sake of time, I think I'm just going to buy a cheap sata harddrive.
3rd Update
So here's the final photo of it running with 2xx7970's
I'm still waiting for the riser cables to come in to mount the other 3 cards.
I haven't uploaded the videos of me building it all just yet (btw I sucked at putting it all together XD)

Slush's pool, can anyone simplify the whole reward system?

Hi! I'm kinda new at mining bitcoins since I switched from BTC Guild to Slush's pool and the whole reward system got me confused a bit.
I'm using GUIMiner and I have about an average of 570Mhash/s (Radeon 7970 GPU). I read through some threads on reddit and other forums on how does the whole pool work but I still don't understand it, I've been mining for the past two days and my Unconfirmed rewards are stuck on 0.00000919 BTC as well as my total reward. Meanwhile my confirmed rewards are still on 0. (http://imgur.com/xoLZ0Yb) The estimated reward changes obviously but my question is why am I not getting any confirmed rewards?
EDIT: Here's also a screenshot of my GUIMiner, please tell me if I have anything set up wrong - http://prntscr.com/2tusck

Is a 7970 still decent?

Hey all recent PC builder here. A couple of weeks ago i built my first pc. A couple of years ago my buddies and I decided to try bitcoin mining and we bought 2 7970's. Needless to say the venture was a total flop and after years of gaming on console I decided to bit the bullet and jump on board. Since I already owned one of the cards I used it in my build: RAM: Crucial Ballistix Sport 8GB Kit (4GBx2) DDR3 1600 CPU: AMD FX-8320 HDD: Hitachi Ultrastar 1TB GPU: Radeon HD 7970 (Sapphire) MOBO: MSI Socket AM3+/AMD 760G/DDR3/CrossFireX/SATA3 and USB 3.0/A&GbE/MicroATX Motherboard 760GMA-P34 (FX) Monitor: Acer G226HQL Bbd 21.5-inch.

Should I upgrade my AMD 7970 to a GTX 1080 with my current build?

I have an old bitcoin mining rig that in its hayday used two water-cooled 7970s. Only one 7970 is still working and I'm wondering if it is worth upgrading just the GPU or waiting to upgrade everything. Here is what I currently have.

I mostly play Mechwarrior Online but above medium settings the graphics card glitches and occasionally shuts off. Additionally, I play around with hacking CTFs and I occasionally have to crack a hash.
What would you recommend with $1000 US? I really liked how quiet the watercooled system was but didn't like the hassle of cleaning out the water. So I was looking at the a hybrid like this GTX1080. Does it still run quietly or should I save up a little extra and get something with more overkill?

Edit: Forgot to add the optional mesh side panel with 4x 120mm fans
I already have the motherboard, processor, storage and power supply.
Remembering that these are Australian prices, how does this build look for a general purpose workstation / folding / gaming rig? It's main goal is for 120FPS on 120Hz monitors in eyefinity (Once you've gone 120Hz you can never go back), and compute (fold/mine) like a mofo, but I also work on it. (Autodesk suite, Premiere, 3DSM, SolidWorks, Inventor and more)
I would have liked to have gone a little further here and there, but I have to draw the line somewhere. To be specific where I would have liked to not cut corners:
The quadfire dilemma I had not originally planned to go for quad 7970s, the aim was just trifire to push me near that 120FPS for eyefinity, well beyond in the most intensive games for a single monitor and reduce microstuttering. I did not like the idea of the cards trying to peel hot air off the PCB on its sibling card like they were suffocating and suffering from asthma, so I planned on using an Asus Rampage IV Extreme, using slots one, four and seven to allow a one expansion slot gap between each card, in a Raven RV02 (non evo). Then my buddy (who also does Bitcoin mining) pointed out that if I kept the gigabyte board I would only spending an additional $0~ to $200~ (depending if I sold the Gigabyte board) by NOT purchasing the much more expensive Asus board and getting a fourth 7970 instead. We worked out the math and the extra card's Mhash/s would pay for itself in two months. Noise and heat aren't a huge issue as it's only temporary until I sort out the water loop. I'll also be getting a bit more gaming performance (when it works) and my general workstation tasks like rendering (V-Ray RT, SW etc.) will also be happy with the extra GPU compute power.
Displays
I have a HighGrade triple 24" stand and had to return the monitor I just bought, and am still yet to decide 100% on which displays but I am leaning towards three BenQ XL2420T 24" 120Hz 1080P monitors. Unlike the 120Hz Samsungs, they have VESA mounts and unlike the 120Hz Asus monitors, I'm not paying a premium for Nvidia 3D Vision that I'm not going to use. Really looking for suggestions/recommendations here!
The case The 650D can fit a thin 280 rad in the top & 120 on the rear. With the HDD cage removed, 200 in the front or 240 on the floor, perhaps a combination of both with some modification (though unlikely, I enjoy a challenge). I could make it nice and neat, but I think I still prefer a chiller under my house with lines routed through the floor. Thinking of using a quality 1/4HP or 1/10HP Aquarium chiller for the job (only a couple hundred more than a good radiator setup). I'm still not 100% set on the 650D and open to other case suggestions. I appreciate the functionality of the Switch 810 but I do not like its aesthetics or size at all. Caselabs are too expensive once optioned and shipped to Australia. Very open to suggestions here also.
Thanks!

Please note that the only parts I had to buy were the Prodigy case, ITX motherboard, Seagate HDD, the 230mm Fan and the optical drive. Also the prices don't reflect what I/others paid. Also I live in Australia; however the AU partpicker was missing some items.

Other notes are that I would strongly advise AGAINST using this motherboard, I had to RMA my first one. The replacement was supposed to be revision 2.0 however is 1.0. This is why I purchased the 230mm fan (in hopes of avoiding another fire!)
I didn't end up using the SSD as its just an HTPC/miner. It mines roughly 690Khash/s on the 7970; and around 110Khash/s on the APU (mining with Scrypt for Litecoin, not SHA-256 for bitcoin) 7970 hovers around 68-74 Celsius with room temps between 23-28C. No thermostat on VRM's unfortunately.
I feel confident this build is complete, no parts to add. I use Filezilla server as a file server as I can access this from anywhere in the world The A10 is at stock speeds as I don't want to push the VRMs on the motherboard and risk another fire. This gives more than enough power for blu-ray decoding, and other HTPC duties.
Very happy with this build. If anyone has any questions or comments I'd be glad to hear the feedback. Thanks

What's the difference between a $400 7970 and a $600 one?

Also applies to everything in between. Let me see if I understand this correctly: A more expensive 7970 will be factory overclocked higher, from say 50mhz to over 100mhz or so, and it will contain this third party's cooling system. So all that's different really is the clock speed and fan style? You can technically save 100 bucks and overclock yourself right?

exhibit b: http://www.newegg.com/Product/Product.aspx?Item=N82E168141614191
I ask this because I'm on the verge of returning my gtx 680. I get a 50-150 dollar discount, a little better or slightly worse performance depending on the game(i.e the same), an extra gigabyte of VRAM, bitcoin mining ability(I'm on campus housing with free electricity), and 3 free games. Good choice right? I'm just going to get the new card with billmelater, then when I receive it Ill ship the 680 back for a full refund, and when it processes I'll pay off the 7970. Good plan or great plan?
