Windows XP 32 bit or 64bit?

[otaku]

biggest problem with 64 bit OS is gonna be compatibility mostly with accessories and some programs. My alienware did not have 64bit as an option for this reason aw tells me. Sucks though cause I have 4gigs of ram and a 1gig turbo stick as well (5gigs!) however perhaps later I can upgrade get 64bit later. For now 32bit is fine you'll get 3.5 gigs
