if you go Dell, be sure to check
www.gotapex.com now and then - they seem to be able to pick out the good deals (well, they look like good deals to me - especially if your other alternative is going to the Dell website directly). Not all the machines are good for gaming but if you check them now and then you'll eventually find a decent system (and in case you've never been there, that page directs you to Dell's website, and they carefully tell you what links to click at Dell to get the good deal - gotapex is not selling stuff, it's from Dell - though maybe they get a cut for directing you there?).
