What is your budget? I picked up an HP gaming laptop for $850. There are gobs of deals that can be had. Now, in picking my laptop, I made sure that the performance and screen resolution would be adequate for my gaming. That being said, most games just don'.... grip me. I play Civ V, I'm going throug Mass Effect finally. I play some Source games and Skyrim. That's about it. So I went with a 16x9 screen, and an nvidia 650m w/gddr5. If your budget gets you into the $700-$900 range, you can get a pretty great system that will game pretty well.
Just be realistic on your gpu and your screen resolutin.
