Re: RAM Question
you could upgrade to 4gigs of ram, but with a 32-bit OS, it would only recognize around ~3.5gigs of ram.
for the OS, xp is less of a resource hog than vista so it should run smoother, but it is nearly 8 years old now (not worth it now IMO). i would just take the step into w7 now. i think youll find that itll run a little smoother than vista, and overall, just like it better.
