I suggest a p4 if you prefer a quiet system. The stock fan turns about 1/3 slower, and I use a quiet L&C 350 watt power supply ($17.95 shipped at dealsonic). You can get a jumbo swiftech or alpha heatsink and use an 80mm slow turning fan for the amd, or a zalman rpm fan adjuster for the stock amd heatsink. Only $6.95 at fry's electronics.
