Hey guys, Well, I've been stuck with Windows XP SP3 for quite a number of years now, and since I've recently had small upgrades and I'll be getting a new monitor soon, I'm wondering if I should upgrade my OS. Should I upgrade to Vista or Windows 7? For each, which "version" should I upgrade to? Also, if I upgrade to either one, will my harddrive (all my files) be wiped? My external isn't big enough to backup everything from my internal. :\ I'm not sure if you guys need my specs, but if so, let me know. PS. Already ran the Vista upgrade test. All green.
