You know NVidia and ATI release a new design every couple of months now (it seems)? Almost impossible to say what the “best” is, since the “best” keeps changing.
Choosing a card depends on 1) budget 2) what apps you use most 3) what apps are most important to be fast.
If it’s just pIllusion, then I would say buy a fairly new NVidia-based card. Not the absolute latest (since you’ll pay a premium for that) but something fairly new.
