You should overwrite. Especially for gaming, running apps in 2k isnt a hassle as it once was with incompatabilities. I am just sick of the "kiddy" appearance of XP(though i know u can change it) and it takes a lot of my resources. I first had 2k installed, then overwritten to XP, but now I am going back, because I dont see any major reason(s) to stay with XP.
