If that's your thing, personally I spend too much time on my PC to waste hours for a dollar.
The PC does all the work, it requires for you to do 0 actual work. If you have 2 GPUs, you can game on 1 while the other does mining. It's not a dollar a day. You already have 3x 470s, so you can just get 3 7970s! If you listened to me last year, you would have had your HD7970s nearly paid off.
2 7970s can make 1350 MegaHash/sec overclocked. That's $150 a month. Less 480W an hour electricity cost (2x240W each at 1150mhz) and you are walking with ~$100 a month in pure profit with only 2 7970 OCed. In 12 months that accumulates to $1,200. It's been 13 months since 7970s launched. Put 1350 in the missing box and see what you get a month.

Now if this continues at this rate, in 12 more months, that's another $1,200 made from just 2 7970s. So what you are saying now you don't care about $2,000-2,400+ in profits over 2 years doing 'nothing'? People here use their GPUs for Folding@Home and other projects for fun, while burning through hundreds of watts of electricity. With BTC, your GPU makes you $$$. The greatest GPU feature
ever. You can now buy
almost 3x HD7970s for the price of a single Titan, get 6 free games and game on 1 7970 while the other 2 7970s are mining 24/7. It's great that NV users ignore this feature. More coins left for us. :biggrin:
I'm looking forward to all the howls of protest on that one from loyal NV fans.
They'll sell every single one. You know how many people might sell their GTX680 SLI/ 690 to side-grade to the Titan just to escape SLI? Also, what about all those high end GPU enthusiasts that spent $600-660 on GTX680 Lightning and Classified? That was just on the GK104. Benchmarkers across all the high-end PC gaming forums. When NV launches the world's fastest card "You gotta pay to have the latest and greatest, early adopter premium be damned". When AMD does this, "OMG, they are ripping us off." If AMD didn't launch HD4870, GTX280 would have sold for $649 for an entire time before NV replaced it with the 285. I am surprised it took NV almost a decade to realize that their fans would be willing to pay nearly a grand for a single GPU. Should have kept going starting with 8800GTX Ultra.
AMD's delay in launching HD 8000 series is going to hurt us - the consumers. I don't know what the hell AMD is thinking.
Based on some of the comments here AMD is on the verge of bankruptcy and if they disappeared, things would get
better for us. Intel would
lower prices to entice more people to upgrade, same for NV since they'd need to give users reasons to upgrade.
I think right now AMD needs to focus on re-writing the memory management / driver for entire GCN series. No point in releasing HD8000 when that GCN's performance hasn't been fully optimized since HD8000 would be starting off on existing architecture at minimum. Also, the Titan will do little to change the standing of HD7000 vs. GTX600 unless NV lowers prices. When GTX690 launched, it wasn't really something that impacted what went on in the market of $100-500 GPUs, except for the 1% of users going GTX680 SLI/HD7970 CFX. Then again, we shouldn't underestimate the marketing/hype of Halo Kepler card to the average Joe, who will surely once again automatically assume that every single Kepler card in every price level below $900 must then be superior to AMD's.
Since Kepler is a more efficient architecture per watt, I can't see what AMD can even do to release a single GPU card that can compete with it until they hit 20nm node.
