It’s so fast that your enemies won’t know what hit them. The Alienware M18x can be configured with two Nvidia GeForce GTX 580M GPUs commanded by an overclocked 4-GHz Intel Core i7-2920XM processor. Also on board this 18-inch rig is a generous 16GB helping of RAM plus dual 7,200-rpm hard drives linked in a RAID 0 array. But on to what really matters: the results.
All this firepower under the hood helped the Alienware M18x blow away other gaming rigs on our benchmark tests. This 13-pounder notched a whopping 158 frames per second in Far Cry 2—at full HD—about four times the category average. We tried in vain trip up the system by streaming the Iron Man Blu-ray to a nearby TV (via the integrated WiHD adapter and receiver). The M18x even averaged 60 fps in the demanding World of Tanks game. Any way you slice it, the Alienware M18x is top dog.
