Alienware is a waste of money, it's just a boutique brand much like Voodoo Computers of Calgary - which was purchased by HP.
Alienware and Voodoo coincidentally also make some of the most ugly computers ever imaginable with about a 200-300% markup on what it would cost you to put together a similar system (including laptops) yourself. Alienware and Voodoo also do nothing more than use off-the-shelf parts and OEM Taiwanese models and slapped them into cuystom cases with fancy paintjobs. You'd have a higher quality and better designed computer actually buying a DELL proprietary design.
The videocard is the essential part to look for in a laptop as it is rare for a laptop to have a gaming videocard. If you really want to spend about TWICE AS MUCH than what it would cost to get similiar performance just for the boutique name brand, then fine, go get Alienware but as far as I'm concerned both Alienware and Voodoo PC are the biggest wastes of money and PC buyer can make.
The best model Alienware has is the Area-51 m15x which *starts* at $1499 but is completely neutered (ie: 256MB 8800M GTX). If you want a 512MB 8800GTX, it's *surprise* add $500. It's the same for most options. In the end, if you want a good gaming machine, it'll end up about $2500-3000.
There are comparable Gateway models with 512MB 8800M GTX cards that only cost $1200 complete back in December with sales.

It's not on the Best Buy Canada website but it was in Canada Best Buy stores a few months ago. If you want more power, you can then just slap in your own CPU upgrade ($300), sell the old one...and you have a computer that blows away the Alienware in speed at 1/3 the cost.
