Windows 2003 Server 64-bit gaming OS? Does anyone run a 64-bit OS as a gaming desktop? My primary motivation for running a 64-bit OS is I'd like to be able to use my full 4gb of RAM (XP shows 3gb) with no loss in performance. System specs: I've got a Core2Duo e6600, 4gb RAM, and a GeForce 9800 GTX+ 512mb video card. I've done some Googling, and some people have posted in various fora about running Win2003 server as a gaming platform, and that it can actually be better than Windows XP for performance and resource requirements. I'm curious if any of the folks in here have compared Win2003 server 64-bit with XP, dual booted, benchmarked, gamed, whatever. I tried the Win7 beta, but the 64-bit version wouldn't install; I kept getting: "Windows could not collect information for OSImage since the specified image file image.wim does not exist." ... which seems to be a common error, again based on Googling.
