ATi is switching everything to 65nm. Nvidia is going from 90nm to 80nm with the 8900's I think, it could be that both the 8800's and 8900's are 80nm. But who knows anyways, I do know that you, I, the video card companies, and the rest of the world all know that these cards are deffinately getting out of hand with heat and power consumption, so natrually the "current" manufacturing trends are going for smaller, less power consuming, yet powerful gpu's. I really don't want to have to buy any PSU that is over 1000 watts, ever.
