I gave up on ATI after I had an X1300 fail and then the 2nd one I'd get all these red pixels in WoW. Only got them in WoW though. Checked the forums and everyone said you have to run the old drivers, just keep going backwards till you find one that works.
Screw that, went and got an 8600GT. I was a die-hard ATI fan, I'm leary to go back now though.
