@vesuvius:Thanks for the tip, I'll see if I can track it down later. Now I have my hands full playing with VS 2011 Dev Preview. But now I want to build a new desktop from scratch around the GTX 590. I'll likely settle for a GT 520, and then when I can put all the cores to work then consider the GTX560Ti, or the GTX 590 (hobby project).  But I guess I'll have to look at the AMD solutions as well. Haven't had to build my own desktop in way too long.
