I am currently running dual celeron 400s @ 450mhz(until I find better coolers than the stock intel ones, stablility is more important for me) and NT4 SP5 128bit with a Creative Labs TNT2 Ultra clocked at 180/205(using powerstrip). With Q3 setup with smp enable at 1024x768 with 16 bit colors and textures and everything else graphically maxed I get 52fps. With SMP disabled I get 47-48. What I notice is it smooths out the parts where it used to bog down(right after the play machineguns JohnC in the demo). I havent tried running them at 500 or above but I imagine the gain is small due to hitting the fill rate of the TNT2 has already been achieved.
