Yea I just had that 520 left over from my old PC which was udder shit. I had a rig that was running an E2200 2.2ghz dual core cpu, 4 gb of cheap ram, a 320gb hdd, and that 520. I'm leaning towards getting the GTX560 since it's cheap enough, and seems to meet everything I want in gaming. I'm not looking to spend over $150 on a GPU.
