I'm not concerned much with TC, I just want to get what I can out of what I have/can afford. I would not fold the CPU at the same time unless I could spring for a 6/8C, and dedicate say 2 cores to GPU management. I don't have that much extra money though. If I remember from when I had my last GTS 450 folding, it was around 8-10k PPD, I don't know if it has changed since then. Its power usage was pretty low and it was cool and quiet as well, thats why I chose them in particular.
