I just ran the FEAR test at 1920x1200, max detail, high quality, 4xAA/16xAF, on my GTX at stock (575/1800) on XP
Average 86, Min 44, Max 209
I know the GTX is a bit faster than a GTS640, but my scores are double your o'clocked score.
Must be the vista driver, even that nvidia human head demo i get like 6 fps, in xp its more like 22 or so.
