I have decided to use bootcamp because I want to play some games on my iMac but am nervous because of the Windows install. Is it possible to do a minimum install of Windows XP SP2? Should I be worried about corrupting my Mac if all I am using it for is installing and playing games? Also, would an antivirus program be recommended for installing on the "PC" partition side? AVG Free maybe? Lastly, how much should I partition for games? 10gig? 15gig? Any help anyone can provide would be much appreciated as well as experience with Bootcamp and gaming. Thanks!
