New computer recommendation

Howdy y'all! I'm finally getting a new computer after so many years. I'm not so much of a techie and was wondering what do you guys look for when getting a new computer? Thanks.

lotta ram, at least 1 gig so pc wont hang on large graphics.
xp pro sp 2... for security and more power.
AMD processor the best for speed and graphics.... i fried 2 intel's
7200 rpm hard drive...80 gig is fine
asus motherboard- just a recomendation- not mandority.
all this is for fast graphic applications that need power.
400 or higher power supply.
good graphic card.
tigerdirect.com - is good for puter stuff.
any other questions feel free to ask away.
