Looking for a cheap gpu (under 200, preferably as cheap as I possibly can), but I need NVIDIA since I'm going to be using it nearly exclusivaly for CS6, which uses the CUDA acceleration. I was thinking of getting the gtx 560 448 for $170 on newegg on sale, but the deal ended. Should I get a normal 560? WHat about the newer gtx 650s or a 550? I don't need the best gaming preformance (Mainly play tf2, cs:s, l4d, portal)
