ATI based cards and SMP..?

Do ATI cards support SMP yet? I havent noticed anything on this topic in a long time. But If I recall correctly, only nVidia cards did.. r_smp on Quake 3 and Quake 3 based games would not work unless you had an nVidia card.. Is this still the case?
 
If your referring to 2D apps or Pro3D applications then yes, ATi's boards do perfecly support and take advantage of multiprocessing. In-sofar as games are concerned I've no idea.... the only game I know of that ever supportd SMP was Quake3 and it's implementation was extremely minimal and pretty crappy to be blunt.

If I recall correctly they removed SMP from the later revisions of Q3 in fact.

in Q3, the difference between SMP enabled and non enabled is a few frames at most. Hardy any SMP action at work really.

From what I've seen one more frequently loses performance with SMP in Quake3... sometimes to a hefty degree due to the overhead and bandwidth contention between processors.
