Alienware  has officially declared about two new models of notebooks, Area-51 m15x and m17x, as “the most  powerful notebooks from all  existed”. The  number of model name corresponds to the diagonal  of display  (15,4 and 17 inches), they are similar on many technical descriptions: both notebooks will be equipped with the Core 2 Duo Extreme processors, NVIDIA GeForce 8800M GTX video card, 667 MHz DDR2, writing Blu-ray-drive (in Area-51 m17x model or writing DVD-drive in m15).
One of the substantial differencies is that there will be two hard disks in Area-51 m15x, and three in m17x. Their keyboard has beautiful LED-illuminating  and possibility of changing its colors. Price and release day are still not known, however there are already lots of official images and photos which you can find further.
