Yes, I agree, I've noticed no difference in performance, only a slight fps drop. I went back to the 87.76 drivers, as they perform faster than the 96.xx drivers. I'm disappointed that my other 7900GTO card out perfoms this one, when this one should be faster.. SLI/MultiGPU doesn't do squat, in the performance area at all. (At least not with the Linux drivers, but in Windblows, there is an increase, when I run 3DMark06. On the same system, using SLI/MultiGPU mode)..
One just can't win.. Great card, stuffed drivers..
