Summary: The Alienware M18x is a notebook built for gaming and performance enthusiasts, plain and simple. This isn't a machine designed to strike a balance in power efficiency or portability by any means.
Pros: Gorgeous good looks, Exceptional build quality, Top-shelf components, Great lighting and AlienFX, Beautiful 18-inch LCD, Killer performance
Cons: Pricey, Big and power hungry, Small range of GPU configurations
Summary: To paraphrase Samuel L. Jackson in Jackie Brown , if you absolutely, positively need to kill everyone at the LAN party, accept no substitutes. If you can only afford one GPU, the $3,300 M17x is a better option, but its chassis can only accommodate a single graphics card.
