Mmm... Total system load difference in FurMark between a 780 and 7970Ghz; 11 watts. The 290x will be about 21GFLOPs per watt like the 7790 was, if not even more efficient, and sitting on 5.6TFLOPs puts it at a power usage 14w higher than the 7970Ghz at most (270w total worst cast)
So you say 22 slots, I assume this means 22 cards, so 22x25 = 550w/h
550w/h x 24 x 30 = 396kw/h per month.
Maryland's average energy bill is about 14 center per kw/h.
396 x .14 = $55.44 per month or about the cost of a 780 per year ($665.28)
This is all well and good... Until based on the benches I can find that pit a 7970 vs a 780 in F@H, the 290x will absolutely murder said 780.Found Benches (Click to show)
The 290x at 2816 shaders is a full 40% stronger than a 7970Ghz. That would give the 290x a score of, in order, 56.6, 14, 35.5, and 196.6.
The 290x would use about 10% more power than a 780, but also be on average 53.5% better. Heck, and that percentage, it doesn't need to increase performance over the 7970 at all.
So really, if you're going for raw PPD/$, the 290x will get you there a whole lot faster. Certainly will do it for the one card less you could use to pay for a whole year of power.
And this assumes the 290x even cost as much as the 780 in the first place, we still don't know.
So ya, get cheaper and more efficient cards and stop complaining about the super-high-end cards power requirements. Seriously... When the 580 did it, it also had the compute to back it up. Now the 290x is doing it and... it has the compute to back it up. Go figure. So did the 7970.
Oh and we'll just add this... BusterOddo's argument was the price of a card vs the yearly cost in energy. If you really did burn $14,300 on 22 780s, you are not complaining about a $670 a year extra energy bill. Probably because your energy bill from them is already at $6,700 per year doing 24/7 folding.
GTX 780 vs R9-290X for folding is a Null Argument.
Oh good, you're overclocking too. You just lost every right to complain about power usage ever.
I want one of these
honestly. Just replace my entire Eyefinity setup with one of them.
4k, IPS, 40-bit color, plus all the usual UltraSharp perks, mmmmm. A shame about the UltraSharp Price, I'll never be able to afford one.
