Why shouldn't you stick a pair of HD 6990M's in an 18.4" laptop, as long as you don't mind lugging around a 12lb laptop from power outlet to power outlet.  Seeing as just a few years ago 12lbs was not an uncommon weight for a laptop that does represent a great design on Alienware's part.  The comparison that AnandTech was most interested in was between NVIDIA's GTX 580M and AMD's 6990M to see who can hold onto the dual GPU mobile performance crown.  Who shall triumph?  Read on to see.

"In our first run with the Alienware M18x, we sat down and took a look at the notebook itself along with NVIDIA's current top shelf mobile graphics part, the GeForce GTX 580M. We came away from the experience with mixed impressions of the M18x itself, a notebook that is by all means incredibly powerful but also seems to lose a lot of the balance that made the M17x R3 so desirable. On the other hand, the GeForce GTX 580M wound up being the fastest mobile GPU we'd yet tested, made only more formidable through the SLI configuration the M18x enables."
