Alienware M15x

Gaming laptops are a curious breed. Over-priced and under-powered compared to their desktop PC cousins, and heavier and bulkier than your average laptop, they’re the definition of an awkward halfway house. But if you’ve got your heart set on a mobile powerhouse, then the Alienware M15x could prove the machine of your dreams.

The M15x’s specifications alone will be enough to leave many fumbling for a credit card. One of Intel’s lightning-quick Core i7-720QM processors buddies up with 4GB of DDR3 memory, a 64-bit copy of Windows 7 Ultimate and Nvidia’s not-quite-top-of-the-range GTX 260M is the graphics chipset of choice. In fact the only let down is the 250GB hard disk, but even this makes up for its stingy capacity with its speed – it's a nippy 7,200rpm model.

As you’d expect, the M15x is one seriously fast laptop. The Core i7-720QM’s default clockspeed of just 1.6GHz might not sound that quick on paper, but Intel’s Turbo Boost technology saves the day. Depending on how many of its four processing cores are in use, it’s capable of ramping up the processor as far as 2.8GHz. It scored a highly impressive 1.51 in our application-based benchmarks.

The GTX 260M isn’t the fastest graphics chipset on the block – the pair of ATI Mobility Radeon HD 4870s in the Asus W90 leave it and its big brother, the GTX 280M, for dust – but with a Core i7 behind it, it’s still plenty fast enough for all but the most obsessive of gamers.

Crysis is about as demanding as games come, so it was impressive to be able to run our benchmark at the Alienware’s native resolution of 1,600 x 900 pixels, set details to Very High and watch the action unfold at a creditable 19fps. That might not be anywhere near smooth enough for enjoyable gameplay, but drop detail settings to the still-gorgeous High preset and the slight jerkiness disappears completely, with the frame rate never dropping below 21fps and averaging a playable 31fps.

Alienware has matched the M15x’s gaming credentials with imposing looks. The aggressive styling is more Batmobile than desktop replacement, with its precise, angular design meshing well with the silvery grey lid. Even the combination of the matte black interior with the edge-to-edge glossy screen is perfectly judged. And, if the M15x wasn’t eye-catching enough already, the AlienFX lighting glows from every angle.
