Hi i have problems that the games lag with my pc gaming rig here are my pc specs.

gpu: nvidia gtx 590

cpu: amd phenom 2 x6

power: 900 watts

ram: 8 gb

motherboard: gigabyte GA-870A-UD3

I have done thing like ending background tasks and clearing my temp folder. Any help will make me very happy since a gtx 590 isn't very cheap.
