Hi Mac Friends! After 14 years of Windows the time has come for me to buy my first Mac. (YAY!!) This Mac will accompany me through university, freelance work and the many hours of gaming ahead! I was wondering which is the best Windows OS for gaming? Games I have ordered are, Orange Box, CS:S, Fallout 3, Crysis and I was considering getting GTA4. I currently own 32-bit Windows XP Professional SP3. Having read many articles (mainly a year+ in age) I am unable to reach a suitable decision so call upon you guys for some help. Here are the specs of the Mac I will be buying: I've read many things about Vista x64 being good but then others saying XP... I'm confused and would like to know which will provide the best gaming experience, whilst utilising the most from the available hardware. I express no interest whatsoever in Windows 7. Also, Any recommendations for hot games are appreciated!! I've been unable to play games for a good 6 months now. Before that, it was only CS: Condition Zero! on minimal settings!!!! I will be buying Modern Warfare 2 once it is released : ) Cheers!
