alienware for that price will SUCK, my PC in my sig cost me 2 grand to build, and at the same time, my sis bought a alienware PC for 5 grand, guess who's is faster and performs better? my cheaper built computer.
anyways, back on topic. check out ibuypower.com you don't have to build one yourself, but at least with the place, you can pick out all the goodies that go into it and they build it for you, then ship it to you, all pre built.
