  • The MSI GT80 Titan SLI is a powerful gaming laptop, and the first we've seen with a mechanical keyboard, but top performance doesn't quite overcome a hulking, awkward design.

  • With its face-melting performance, a fantastic mechanical keyboard and upgrade-friendly chassis, the MSI GT80 Titan SLI is the gaming laptop to beat.

  • This is the fastest gaming laptop we’ve ever tested thanks to top-notch components in every department, and its mechanical keyboard makes the typing experience better than every competitor. It’s big and heavy, though, and painfully expensive. Alternative configurations with the same chassis offer better value but overall this is still an aspirational product for the privileged few - the rest of us will have to make do with lugging our PCs round to LAN parties.

  • Big, bulky, and ostentatious as heck, the Alienware 18 is the ginormous gaming laptop you want to use to show off your riches on the game grid.

  • Alienware once again lives up to its reputation as a manufacturer of high-end notebooks. The successor of the M18x R2, simply called 18, not only impresses with its dignified design but also with the excellent performance. Nothing comes close to the performance of an SLI system with two GeForce GTX 780M GPUs at the moment. Combined with a quad-core processor and a Solid State Drive the notebook even manages the most demanding applications. The retail price is consequently very high.

  • Packing the best of everything -- including two state-of-the-art GPUs -- the Alienware 18 is the quintessential gaming notebook.

  • The Alienware M18x R2 is definitely a superlative notebook, but calling the massive 18-inch unit a "notebook" is stretching the term. At over 5 kg, the M18x R2 is essentially limiting the user to indoor use only.

    Still, no one can deny its mighty performance. Thanks to the overclocked Ivy Bridge processor and the two Radeon HD 7970M GPUs, the high-end machine handles every task easily and painlessly. All currently available games can be played with maximum settings.

  • Sporting dual Nvidia graphics cards, crazy-fast dual SSDs and a show-stopping 1080p display, the Alienware M18x R2 is the gaming notebook dreams are made of.

  • The Alienware M18x R2 is definitely one powerhouse of a computer. It has a fantastic 1080p display, top-of-the-class performance and good battery life. While quite expensive, it makes a great gaming laptop and will handle anything you throw at it.

  • Alienware again pushes the boundaries of laptop performance (and price) with high-end parts and a great-for-gaming 18-inch screen.

  • In the beginning, we were skeptical of the M18x. Alienware's 18 inch "monster" does not exactly fit into any of the current trends, and most buyers do not go above the 17 inch range. However, after our in-depth testing of this laptop, we have to conclude that the M18x has a lot of potential.

  • To paraphrase Samuel L. Jackson in Jackie Brown, if you absolutely, positively need to kill everyone at the LAN party, accept no substitutes. If you can only afford one GPU, the $3,300 M17x is a better option, but its chassis can only accommodate a single graphics card. But if you can swing for two GPUs, then the M18x is the way to go. From power to weight to price, this notebook simply has more--the most--of everything.

  • - The AS8943G's screen, including its borders, is covered in glass, providing an authentic home-theater look.
    - Very good battery life for a media-center laptop.

  • - The generous 3 x 2.2-inch touchpad has a glossy plastic surface that was relatively easy to use despite some friction.

  • Acer's Aspire Ethos is certainly a desktop replacement class system as it is certainly larger and heavier than many laptops. In exchange for portability, it offers some solid performance thanks to a quad core processor, fast graphics processor and larger high resolution display. The added aluminum increases the look and feel but the design is hampered by a number of small items such as narrow viewing angles, a single trackpad button bar and a price tag that is well above Acer's typical price and slightly above smaller competing laptops.
