Alienware 18-inch,17-inch and 14-inch gaming laptops...

Alienware invades E3 style-

There's no need to fear an alien invasion, not when they come from the planet Dell. Alienware comes in peace and is interested in one thing and one thing only: high-performance gaming. Maximum PC Online Managing Editor Jimmy Thang probed Alienware's booth at E3 to take a look at three new gaming laptops, including a 14-inch model, 17-inch model, and a giant 18-inch SKU.

Alienware claims its 14-inch model is the "most powerful 14-inch notebook in the universe." It's also uniquely designed and looks different from previous generation Alienware systems. There's an anodized aluminum cover, magnesium alloy body, and an overall industrial design. There's also a lot of metal on the inside to help keep components cool.

Lighting has been changed, too. There are now 10 customizable lighting zones, though if you're not into that sort of thing, you can turn them off. Alternately, game developers can tap into the lighting zones and, say, make them blink red if you get shot by an enemy. Cool stuff.

The 17-inch model kicks things up a notch and comes standard with an Nvidia GeForce GTX 765M GPU (you can upgrade to a 770M or 780M), and of course Haswell is inside.

Choosing the 17-inch SKU over the 14-inch model obviously sacrificies portability, though it also increases the level of immersion since you're working with a larger display. If you really want to go big, however, check out Alienware's 18-inch beast.

Described as the "big kahuna," Alienware says this is the most powerful gaming notebook in the world, period. Unlike past versions of Alienware's 18-inch model, you don't start off with a single graphics card anymore -- it now comes with two GPUs by default. It's essentially a portable gaming desktop.
