you can get an xp 2500+ barton for 81 dollars on newegg. overclock it to at least an xp 3000+. if you read the reviews that xp 2500 chip is unlocked and ppl say they can run it at xp 3200+ speeds with no problem. just be sure to get some artic silver thermal compound, and a bigtime cpu fan like so:

for the ram, zipzoom sometimes has better prices than newegg. i got my corsair twinx pair of 512 xms 3200c2pt strips for 207 bucks...new egg wanted 225 for them.
so, if you want a gig of ram...you can get a nice gig for around 200...the cpu for 80..and a nice asus a7n8x deluxe here

for 85 bucks...so thats 165 for the cpu and mobo, choose your ram...you got about 150 to spend on it depending on your budget ....
hope that helps beer:
