Might want to look at a configuration similar to this: http://www.youtube.com/watch?v=lJFXthMAKKY&feature=channel_video_title Pretty salty, cashwise, but if you want to game on a laptop, you're gonna pay.
There aren't any. Any Laptop that has gaming plastered on it is over-priced. Stay away from anything Alienware. A good ASUS Laptop would do you, but it'll cost 1.5x what a Desktop of the same performance would cost. http://www.newegg.com/Product/Product.aspx?Item=N82E16834230142 http://www.notebookcheck.net/NVIDIA-GeForce-GTX-560M.48313.0.html Alienware has the same model.... for 2000$.
I'll look at the ASUS. I knew right out of the gate the Alienware wouldn't be worth the cash. It's not for me but a friend who wants a laptop capable of playing flight simulator X.
