ASUS makes amazing gaming laptops.
Ive had mine since march of 2009 and it still runs every game very smooth. Laptops can be used for gaming, you just need to purchase the right one. And no Alienware isnt that great, ASUS gaming laptops have the same hardware for half the price.

That is freakin cheap for a laptop that wont stutter, even on crysis.
Graphics performance is on par with a 9800GTX....very good for a portable machine. The whole argument that laptops arent good for gaming just doesnt hold true anymore.
And mine is similar with the same gpu, and Left 4 Dead 2 runs maxed on everything smooth as butter at full screen res.
