    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. :(
