I dumped my ATI card (9600) for a NVidia after fighting for a month. 
The recompiling the NVidea drivers with each kernel upgrade is minor 
compared to the missing 3D graphics and associated problems. (lack of 
game support :) )

ATI's own software does NOT support 3d and I didn't find this out 
until after I purchased the card. :(
