AMD GPU support is pretty good these days, in my experience. The OSS
drivers also work well enough for me to forgo the proprietary ones
(usually), specifically because using xrandr is easier to me than the ATI
Control Center. I have three monitors with a resolution of 4960x1600 with
one AMD card on the OSS drivers and can still do 3d pretty well. (Better 3D
with the proprietary ones)

I'd recommend any newer AMD card with the OSS drivers, else you really
can't go wrong with nVidia.
