Well like I said, Gears of War played perfectly, flawlessly for about 3 minutes. I don't see how everything could be running fine for that long, then suddenly decide it doesn't have enough power. It's not like anything more intense was happening on the screen when it died or anything... it just happened at a seemingly random time, working absolutely perfect 1 second earlier.

Your GPU is definatley not getting enough power, I usually recommend a 600w or higher with a 8800, with more than 30 amps on 2 or more 12v rails.
Core 2 Duo e4300 1.8Ghz (not OCed obviously)
320GB Hard Drive, 7200rpm
DVD+/-R/W / CD-R/W Drive, not sure on the speed
A fan on my processor, one on my 8800, and a fan on the back... about 3x3 inches I'd say
500w power supply (8800 says it only requires a 400w...)
