if you dont mind waiting, and don't want to OC, then i reccomend the q9450, I reccomend that you go with the 8800 gts, if the 9800 isn't already out when the q9450 is, and i reccomendgoing ddr2, since ddr 3 is so expesnsive, you can have 8 gigs for the price of 2 of ddr3, i also reccomend 500 GB hard drive, and i warn you that watts don't matter, the amps and brand does
