To my absolute amazement TRS2004 does not run any better or worse with the latest and greatest Geforce GTX 680 FTW 4Gb than Quatro FX4800 1.5 Gb. I would have expected a major improvement. I think the only difference is my electric bill is going up and my heating bill is going down.
My guess is TRS2004 cannot fully utilize either card. Does anyone know why this is?
