Folks, just wanna say I have not underclocked the card or anything. Asus automatically sets the clock on their 6800 GTs to 350/700.
So, am i outperforming 6600 GTs and if so by 'how much' (performance increase, a lot, not much, etc.)
AMD 64 X2 4200+ @ 2.2ghz
2048mb Corsair PC3200 RAM (2x1gb)
WinFast NF4SK8AA Motherboard
660GB HDD Capacity (3xHDD)
600w Enermax PSU
eVga 8800 GTS 320mb
