ok so what happened. i was planning on playing world of warcraft but heck no i'm not going to pay 77 dollars for 6 months. anyways lets go straight to the question.. i need to install some form of windows to run a game. i'll only use it to play a certain game, nothing more. i was wondering according to this how should i divide my 160gb hd. i'd really appreciate it and if it would make any difference installing either xp or vista. which one should i use and if i install windows will i see a change in the performance. will the comp become slower or crash?? i dont want to screw up this beauty of a machine thanks.
