I currently game on my dad's workstation that he doesnt mind me using. I was wondering if because this runs on Windows XP x64 Pro but is a corporate lisence (not that you would buy in the store) if it would hinder my performance. Every once in awhile there are strange messages that come up, like when i went to install WIndows Media Player 11 it said im using Windows 2003 Server, even though im using Windows XP, and also i dont think there is a SP 2 for this windows version. Anyways, what do ya think?
