I've ordered a new Mac Pro - custom built: 3.2ghz Intel Xeon Nehalem 8gb ram 1TB HDD ATI Radeon 5870 27" LED cinema display The screen has already arrived. The rest is on its way. I'm going to use the Mac side of it for work (photo editing and other heavy graphics work with Adobe CS5 Master Collection). I intend to use a perfectly functional older 300gb 7200rpm HDD for Windows 7 64 bit and games, in particular, Flight Simulator X, with some very heavy duty / advanced addons (hence, no interest in X-Plane): - Concorde X - PMDG Boeing 747-400/747-8 - PMDG MD-11/MD-11F - Real Environment Extreme Overdrive - ActiveSky Enhanced I've used bootcamp and Windows XP on another computer (iMac 27") in an office and seemed to have problems with it overheating. I needed to have SMCFanControl to speed up the fans and prevent the "red boxes" across the screen. Will I likely have the same problems in Windows 7 64 bit on Mac Pro using Bootcamp? I know the performance will be very fast - just want the reliability too.
