Can i run any game on this computer?

The i7 2600k has a intergrated graphic card install by intel and i hate to say this not very good for gaming,also i see the msi hd 6950 2gb gddr5 256 bit , reference to the first answerer, a nice system build, agree the psu is to low for good gaming performance, a 650 watt psu antec true power, coolermaster extreme plus, for the specs as now with the 520 watt it can run on max settings but try to give a little breathing room for gaming at least a 100 watt more psu
