Unless Vista is cheaper, I would suggest XP. If you really want vista then go ahead, but XP takes up less space, so you will have more space for games, plus xp uses less resources, meaning your games will run slightly faster. I would suggest a copy of xp pro sp2, but it is up to you. I am running vista business, and am looking for the opportunity to wipe it and install xp pro, I just haven't had the time or backup space to do it yet. Don't get a 64 bit version of XP(X64 I think Microsoft called it) if you do go that route, as it is not supported by Apples' Bootcamp. Glad to hear you are enjoying your new mac!![]()
This is true. I had problems with XP so I "upgraded" to Vista. This is on my C2D 2ghz, 1gb Ram x1600 iMac. Vista ran like a dog. To get the same FPS rate in HL2: Ep1 I had to turn off Bloom and HDR. Only then did the FPS settle at 32fps (what XP could do with the effects on).
I hear Vista purrs if you have an adequate amount of ram.
But in my experience Vista slowed down game performance, and also took longer to boot than XP. Not good when you dual boot.
