That CPU cooler will let you OC the Phenom II pretty high. Theres a 500GB hard drive for files and porno and then an SSD for windows and games so everything loads super fast! GPU is a GTX480 its often maligned but it provides as much grunt as a gtx570 at a much lower cost meaning we could afford the SSD and stuff.
