Well anybody who uses standard ATI or nvidia drivers shouldn't be here to begin with. Use the Omega drivers, they are a LOT faster, and they're for ATI and nvidia. and ati released a new driver for the x1k series that gives it a 30% boost in opengl, i cant confirm that however because I have never owned an x1k ati card. also 7800gt would probably be better, you can get it on newegg for as low as $279 now, which is an insane deal because the 6800gt is $285
