Also note: Cases, like the Raidmax Aeolus, already have a 500W power supply and great cooling for $79.99. There is also something to be said for buying say an i5 (Ivy Bridge) with a GTX560 and 1866MHz ram (9-9-9-11). All can be done for around $600 or so with a decent Solid State (120Gb), and this will perform most games very well on highest settings (if one doesn't like AMD).
