You know I just wanted to shoot this out there. I picked up for real cheap a 220GT and was going to sell it to a customer of mine. But instead they didn't end up taking it off my hands. SO I am currently using it for a Dedicated PhysX GPU. With my two XFX Radeon 6870's. Besides adding some extra heat to the case.... it is working out pretty well.
I will post some benches when I get up tomorrow. But you know I just wanted to throw that out there in case someone is looking for a cheap solution to PhysX. While it won't do as well as a 9800GT or a 8800GTX or even a 240GT or 430GT the EVGA 220GT is working out wonderfully.
