I kinda thought it was a laptop when I saw it had a 9800M (Mobile) graphics chip.
Most laptops are not really engineered for gaming and as a result overheats.
If you are going to stick with a laptop I HIGHLY recommend the ASUS G74:http://www.youtube.com/watch?v=pGyc36KKdRw
My coworker just picked this up. It is awesome and it has a great cooling system. The back end of it has huge vents to exhaust heat. It is beast of a machine too. Intel Core I-7 Processor and a Nvidia GTX 560M graphics.
