I have a question that may have been asked and answered already but after doing some searching I have been unable to find a specific answer. I currently have a 295gtx installed. I also have a 8800gtx laying around. Can I use the 8800gtx for PhysX (LANPARTY LT X38-T2R mobo, I know its a crossfire board) and if I can, is it a worthwhile thing to do? I have thought about this before, but at the time I was under the impression that I couldn't use the 8800gtx for PhysX, now I'm thinking that I may have been mistaken. Enlighten me Gurus. Thank you.
