Dell could soon add two new gaming notebooks to its Alienware range in the form of a 14-inch and an 18-inch model, according to images leaked on the dell.benyouhui forums. Details are scarce at the moment but the larger model – appropriately named M18x – is said to sport a 1080p display and graphics from either two AMD Radeon HD 6870M chips in CrossFire mode or two Nvidia GeForce GTX 460M GPUs set up in SLI.

Meanwhile, the M14x would join the well-received M11x in combining gaming prowess with portability – only a little more of the former in exchange for a little less of the latter. The notebook reportedly includes a glossy display, combined with matte surfaces, and overall follows the same design cues as other models in the Alienware laptop family. Graphics could come from Nvidia's GeForce GT 555M, AMD's Radeon HD 6730M or Radeon HD 6770M according to the source.

The new models are expected to complement existing 11-inch, 15-inch and 17-inch form factors and come equipped with the latest Sandy Bridge processors. Unfortunately, release dates or prices for the two systems are not yet known.
