XP is decent in comparison to 2k, might consider that...its a little clunky, but 2k is a bit resource intensive...i would say moreso then xp, but im not sure, they're likely equal and im making things up.
btw, heres my XP1600 with 512 of 2700 DDR and a 400w Antec, also 100g 7200RPM hdd, CDRW, DVD-R, and geForce 4 vid card
