Well, I can tell you right now, you will not get a new Alienware anything (PC or laptop) for < $1000. But, for about $1,136.00 (after $75 mail-in rebate, but don't forget about the shipping for $119 (however, free at the moment)) you could get this:http://www.alienware.com/Configurato...de=SKU-DEFAULT
Perhaps when you get some more RAM for it later when you get some more cash.
Another option would be to build you own rig. You could easily build a budget gaming machine for sub $1000 (that is, if you feel comfortable about touch expensive hardware
). Here's a great article on how to do it http://archive.gamespy.com/hardware/march03/bgm/
It's a little outdated (March 2003), but you should be able to find parts that are better and cheaper now.
I used that article to assemble the PC I'm currently typing on. So if I can do, you can too!
