The anodized aluminum chassis is built like a brick house. There is no other high performance laptop that runs as well. It overclocks like a dream and it can be upgraded about as easily as a desktop computer.

Ability to play the newest games at maximum settings and resolution is probably to be expected for over 4000 euros, and all in all the Alienware is about as future-proof a notebook as money can buy. So what is there to complain about with? Lack of Firewire? Not really. Perhaps the price. Amazon sells nicely loaded Dell Alienware M18X laptop with case for $2,349.

The Alienware M18x is a notebook built for gaming and performance enthusiasts, plain and simple. This isn't a machine designed to strike a balance in power efficiency or portability by any means. Dell's Alienware division apparently built the M18x with one mission in mind--to deliver the best possible gaming and multimedia experience available in a self-contained, "desktop replacement" form-factor.

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.

With the highest configuration, gaming performance was simply outstanding at the highest graphics setting for all of the games tested. It is definitely the best-performing laptop that we've tested to date, thanks to the amazing specifications and uncommon SLI-graphics setup. Battery life, as you can expect, with the Alienware M18x is rather poor compared with all other laptops at about 1.5 hours, so you'll definitely want to stay near a power source if you do any portability.

While 17-inch desktop replacement laptops with decent gaming performance are easy to find, if not exactly common, to truly move into the realm of mobile home entertainment center, there's nothing like an even-larger 18-inch screen. Alienware again pushes the boundaries of laptop performance (and price) with high-end parts and a great-for-gaming 18-inch screen.

Comment
NVIDIA GeForce GTX 580M SLI:
Two GeForce GTX 580M (GF114 Fermi) cards in SLI mode. Because of the maximum power usage of 2x 100 Watt of both MXM boards, the GTX580M SLI can only be used in very large laptops.
These graphics cards are able to play the latest and most demanding games in high resolutions and full detail settings with enabled Anti-Aliasing.
» Further information can be found in our Comparison of Mobile Graphics Cards and the corresponding Benchmark List.
Intel Core i7: The Intel Core i7 for laptops is based on the LG1156 Core i5/i7 CPU for desktops. The base clock speed of the CPUs is relatively low, but because of a huge Turbo mode, the cores can dynamically overclock to up to 3.2 GHz (920XM). Therefore, the CPU can be as fast as high clocked dual-core CPUs (using single threaded applications) but still offer the advantage of 4 cores. Because of the large TDP of 45 W / 55 W, the CPU is only intended for large laptops.
2920XM: Fastest mobile Quad-core processor in Q1 2011 based on the Sandy Bridge architecture with an integrated graphics card and dual-channel DDR3 memory controller. » Further information can be found in our Comparison of Mobile Processsors.
18.4": 18 inch display size is a rare and very big size for desktop-replacement laptops. Laptops with 18 inch displays did not exist before 2008. The DTR-laptops can't be carried easily, need much energy but on the other side texts can be read easily and high resolutions are no problem. DTR mainly are intended for stationary usage on desks, where the weight and the energy need are unimportant.

5.64 kg: This laptop is heavy. Especially desktop replacements with 19 inch display fit in this class of weight. This class is too heavy, even for 17 inch DTR.
