Not much else to say really. Pretty much what everyone else has said. Build it yourself, it's cheaper, and not complicated in the slightest (if you can match colors, shapes, and use a screwdriver, you can do it!). I'd suggest parts from Newegg and/or TigerDirect.
If you have the money, and like computers that look like they were designed by an "eleventeen" year old with an alien fetish (at least in my opinion, I think they look awful), you could pick something up from Alien Ware. Though you'd be really over paying for it, and could most likely get something better, for much much cheaper.
For about $800 (give or take, depending on if you need extra mice, keyboards, speakers, monitors, etc), you can build yourself a fantastic machine. I did a few months back, and I'm running everything I've thrown at it (Crysis 1/Warhead/2, SC2, Age of Conan, The Witcher 2, etc) at max (or nearly max in the case of the Witcher 2, ubersampling drops me to 30FPS) settings, at 50+ FPS in 1600x900 resolution.
