Gateway FX6800-01e THat is my gaming computer as of a month ago. i bought it cuz i have no idea how to build a computer. Speed: i ran FOUR games, AA2, AA3, Day of Defeat: Source, and Arma II demo (which specifies that you have a quad core), AA mission editor, Vent, TS, and xFire. I checked the Processor speed and RAM speed and i was using only HALF of the CPU power and 2.78 GIGS of my 3 GIGS of RAM. all with no lag.
granted Vista 64 bit is a piece of SHIT!! it does well running games despite the occasional error. if you have $1000 to spend i suggest this.
