Alienware Area-51 m15x


It's the ultimate and fastest gaming notebook in the...oh, whatever... you know the drill! See inside for the first UK review of the Alienware's 15.4in gaming machine.

It's smaller than most gaming notebooks and thanks to a superb lighting system, it looks the part too. But performance is where it counts and the Alienware Area-51 m15x has it in spades. A generous selection of options means you can tailor it to your...

Alienware M15x notebook


Alienware is one of the most distinctive brands of PCs there is, thanks to interesting attention to detail. Fortunately a move into the Dell family has not destroyed this line of gaming PCs and the M15x still has the traits of something special. From...

Power, design, Alienware FX, build quality

Price, trackpad could be better, battery life

We love the Alienware M15x for being an unadulterated gaming rig that is so exuberant. It's difficult not to be drawn to it's over-the-top looks and attention to detail. But you do pay for it. The lowest spec (which is still fairly impressive) comes in...

Alienware m15x review


The m15x is another out-of-this-world laptop design from Alienware. Is it onto something, or just on another planet?

A striking notebook with some brilliant extras, the m15x just isn’t as good at games as you'd think

Alienware Area-51 m15x review


It packs the most powerful portable parts into a shiny new shell, but is the m15x the ultimate mobile games machine?

A great new design, and Alienware's best gaming laptop to date

Alienware M15x review


One of the best gaming laptops around and comes at a very reasonable price

Core i7 CPU ; Dedicated graphics ; Reasonably priced

Battery life and general portability ; Screen could be brighter

A very competitively priced and specified laptop that should cope with even the most demanding games

Alienware Area-51 m15x review


A powerful solution that makes this the first truly impressive Alienware laptop

Impressive styling ; Powerful performance ; Sharp screen

Poor graphics performance

A powerful gaming laptop, but the graphics performance leaves a lot to be desired

Alienware Area 51 m15x review


The Alienware Area 51 m15x is a gaming laptop that stomped all over our WorldBench 6 benchmark, earning the highest laptop performance score to date and running effortlessly through our current graphics tests.

If you can afford it and you have the muscles to carry it about, the Alienware Area 51 m15x is quite simply the quickest and best gaming laptop we've seen. Game on.

Alienware M15x


Fusing extrovert styling with serious gaming power, the Alienware M15x is sure to impress.

For all its deficiencies, though, the Alienware M15x is a gorgeous gaming laptop. There is stiff competition from the 3.42kg Asus G60Vx, but despite a slightly higher price tag, the Alienware's extrovert looks and fantastic display help it snatch the A...

Alienware M15x review


A stunning machine, let down by being so many upgrade options. If you've got the cash, get a desktop rig instead

Stunning images, gaming on it is a dream, HD graphics

Pricey, endless options push the cost up, no HDMI

Alienware M15x


The latest incarnation of the Alienware M15x gaming laptop is completely customisable, but the version we tested came with 64-bit Windows 7 Ultimate, 4GB of DDR3 RAM and the jewel in the crown, an Intel Core i7 1.6GHz processor - you can boost that up...

There's no doubt the Alienware M15x is a blistering gaming laptop, but it all depends on how much you're prepared to pay, and we're not quite sure who it's for. You're not going to leave the house with it, so why not just get a full on gaming desktop...
