Yep, right now Im running a 750w Thermaltake Toughpower, beautiful PSU, but running an SLI with one of those woudl be nuts.. I would 'personally' jsut stick to using hafl that power with dual 8800's if it came down to that The added 1 KW power is exponential, youll be paying more for the PSU, more for the cards, and your energy bill will go up about 30% on your computer usage (just for computer.. so it might be another 20-30 bucks a month). So, yoru in it for the long haul if you go that route.. it gets very expensive
Hence why I would refuse to get dual AMD cards. Even though they push well over a teraflop of FP computing power. O.O
Then again the 8900's (pair) should do it also and the 8800GTX's (pair) pushes like 900 gigaflops of computing power. =P
AMD is just becomming a real joke. They used to be the top of efficency but they are now lazy. Look at their quad FX setup.
Running 3dmark 06 with a dual FX-74 setup and SLI 8800GTX's pushes a 450-500 continusious load. Now if that was dual x2900XTX it would be well into the 700w rage. And who knows what dual x2900XTX2 (quad crossfire) would do. 800w maybe? O.O
Now here it costs $0.15 for a 1kw/h. So at .8kw/h it will cost $0.12 to run per hour. Given that the average gamer will use it for 6 hours a day it'll cost $0.72 a day to run. With 30 days a month it'll cost $21.60. And that's here in southern MA. Out in CA it'll be even more as power costs more there.
Now with that said you also need to look at cooling the thing. Sure Winter time it's no problem with the extra 800w heater. But in the summer time you don't turn on your 800w heater to warm up the place. You turn on your 5000 BTU AC to cool of the place it just wont handle as 5000 BTU is just able to cool down 1465w. So with the PC making 800w of heat the effency of the AC will only be 2200 BTU not enough to cool down the room. So what do you need to do? You need to buy a new 7500 BTU AC to cool your self down. And what does that do? Adds another 800w of power. But the thing is. Who only runs their AC for 6 hours? You run it 24/7. So at the extra $21.60 a month it takes to run your PC it will cost you an extra $86.40 to cool your house. So now that computer is costing you well over a $100 a month in the summer months!
