So I got my mac pro today. Standard config with 2.66ghz Xeons and 7300 GT card. Also got the 30" cinema display. WOW! What a machine. So anti mac me thinks. First its been running for hours and its NOT hot at all. Feels like no hot air is even blowing out the back. Second its as quiet as a laptop. Makes NO noise at all. Seriously. Third its fast as hell. Got XP running on it as well with some alternate drivers and its great. This all in contrast to my G5 which was loud, HOT and not nearly as fast as this. Best mac ever period. So glad I went into debt to get it. Never looking back. PS: I new this was coming so I sold my Dual 2ghz G5 2 weeks ago for $2700. he he. I made money.
