U better go for Athlon64 3200+ venice core, E3 or E3 revision, they are hard to find, but available, just jump on the retailes head for it, maybe u have to place an order, but going for venice is the best choice even if u don't overclock
U can identify venice, by checking the OPN on it, the model number should be
ADA3200BPxxx (E3)
ADA3200BWxxx (E6 core)
E6 is better then E3, but not a necisity, add a 400W SMPS from colorsit, or VIP as they are cheap & good quality, I check a colorsit with a Multimeter a few days ago, when a friend of mine was buying a PC, with A8N-E, it's really efficient & gave about 360W on 400W claiming
the stock cooling is good enough as long as u don't overclock,
also turn on the Cool & Quite feature, it's a big temprature decreser, for more info take a look here
