Alienware M18x Notebook review

 

The Alienware M18x is a desktop replacement notebook in the truest sense — it's powerful enough to replace a desktop workstation, but it's also as big and as heavy as a desktop PC. It's exceedingly powerful and has the ability to handle almost any...

If you’re looking for a proper desktop replacement -- replacing a gaming desktop, that is -- the Alienware M18x is undoubtedly the notebook to pick. It’s massive and has a price tag that’s painful, but its performance is almost unparalleled.

Alienware M18X

 

The M18x is the like Mike Tyson in his prime, extremely powerful, a little crazy and a class act, if you can afford the astronomical price.

Nearly Beyond Powerful, Connectivity, Amazingly engrossing screen, Build Quality

Price, Cost of Upgrades, Some may feel it needs a redesign

Dell Alienware M18x 18.4in gaming notebook

 

Review Last year, Dell added to its Alienware laptop family and simultaneously expanded the definition of ultra-portables with the tiny-beefcake M11x. This year's new addition, the flagship M18x, now expands the other end of the spectrum.

The M18x lives up to expectations. It feels lovingly crafted around gamers' needs, combining superlative design, build quality, aesthetics and scalable power. But it comes at a cost. The review model's price compares reasonably well to other gaming...
