Hmm I guess I wont do it. I could use the money anyway since my 448 cores is in great condition. I was more of just curious I guess. I'm sure if I play a game with PhysX the single GTX680 will handle it fine. And to the first post no way am I spending money on a 1000watt psu at this time, I just got a 680 lol
My 650watt psu is more than enough to handle the gtx680 and my 4.5ghz overclocked i5 2500k. But I know having a little more would be nice. I would love to get an 850watt psu in the future.
