What should my next game machine be? Should I buy a Xbox 360 or just get Windows for my 24" iMac? My iMac is 2.16GHz with 2 gigs of RAM and the 7600 256mb video card. I also don't have an HDTV yet. I want to play Gears of War, but I also want to play Supreme Commander. Other games on my horizon are Guitar Hero, but I could just get a cheap PS2 and Unreal 2K7 will probably come out on both platforms. I really want to play Half LIfe 2, as well as Team Fortress 2 and Portals. How long does it take to reboot into Windows? It boots and shuts down OSX pretty quickly. Are older games cheaper on the 360 or for Windows (FEAR for example)?
