Hi I wanna install via Boot Camp an XP, but would it slow my MB? I mean working on Mac OSX, start up/shut down time etc...? If yes, how much it'll slow it? I've got MB Alu, 2GHz, late 2008. Generally is it worth to install XP on MB for gaming, I mean, not for real gaming, for that I've got consoles, but sometimes I wanna play with friends CoD:WaW, Crysis etc...
