Hey Guys, I have used and built PC's for about ten years now. I have always used windows machines and i have had headache after headache with DOA parts, stupid mistakes, and just overall windows frustration. I am strongly considering saving up for the next refresh of the iMac. Everyone i know who has a mac loves it. I have the iPhone 4 and i do love it. My biggest concern is how is bootcamp performance of windows games? Is there a noticeable performance difference? Also, how is the heat of the 21" imac compared to the 27? Should i expect the small form factor to heat up my GPU/CPU to 90c and bluescreen? . Are there fan controller programs for osx? Any word on what the new imac will have in it feature wise? Thanks for any help fellas.
