AMD all the way, why ? Because My Athlon XP 3200 64 bit processor running at 2.2 ghz pisses all over my work machines Pentium 4 2.8 ghz machine.

Work machine has 2 gig of ram in it, when running outlook, winamp, telnet, and then i open adobe photoshop or something, it max's the cpu right out, and my music starts stuttering.

I have my home machine here at work, got Outlook Express running downloading home e-mail, winamp, telnet, Outlook, MSN, Firefox and i'm backing up my mp3's, not a stutter on the tunes at all
