http://www.cyberpowerpc.com/ I got my first "my computer" from these people over a decade ago to play Q3JB on, and about 10 months ago I got my current work laptop from them. They specialize in "build to order" jobs, but they have lots of packages up already. You can probably find a cheap one standard, if not, check in on them every day for a week or two. They have pretty good deals based on what they have a lot of.
My laptop is a 19 inch i7 with a geforce, built for video editing (and, incidentally, every video game on the market), so it's probably more than you're looking for, I'll not post the specs. But I like these guys, they do good work.
