Not by much. Its a 50Mhz core and a 150Mhz memory overclock and it's there. That may sound like a lot for other cards, but the 7950GT is cool as a cucumber and reaches speeds of 750/1800 (7900GTX is 650/1600) without any problem. Since the hardware on both cards is the same, the 7950GT and 7900GTX would perform the same at the same clockspeeds. Not a bad deal for $260.
