Hi

I am gonna install/try out some games on my HTPC, but thought i might be better of setting up a dual boot system so I can keep the original install nice and clean.  Has anyone got any opinions on this or guides.  I have both Vista and XP, currently using XP.  I was thinking of going back to vista after i buy an 8600GT and then having a second boot for games.  I'm not sure if games will run better in vista or xp with my system.  Any help appreciated, thank you!!
