First of all WASS!UP! burito
Second if you dont care to much about graphics then you dont need anything fancy i bought a 300$ desktop with a pentium dualcore at 2.8 each, 4gigs of ram, 1tb hard drive, then upgraded to 550watt power supply and a HD5770 all my game settings are set at standard turned my overdrive down and when i play i set fan speed at 75% i take the side of the case off and stays at about 70-75F (seems to get hotter when in windowed mode) the only time i ever get lag is when im in a busy city like uldah and iv'e played for hrs with out having to shut down for cool down
