Geoff Beasley:
a relatively recent (6000 series or better) nvidia based chipset with the
nvidia drivers will be the best inho.
I wouldn't do that. The nvidia drivers have a history of causing xruns.
Not that its that bad though. I have always used the nvidia drivers, and
they work just fine as long as you don't go below 1024 frames.
(the nv drivers, otoh, should be fine.)
