"In last year's battle-of the behemoths, Dell's M1730 took on Alienware's m9750, and with the exception of a few quirks, came out on top. But not everyone is ready to lug around a notebook that weighs nearly fifteen pounds with its power adapter.
Alienware's advantage in portability among 17" gaming notebooks was still noteworthy, even if the Area-51 m9750's battery life didn't lend itself to truly mobile computing. The company now looks to extend its portability lead, with a smaller, lighter 15.4" unit that maintains the high resolution of the former 17" model without sacrificing battery life.
There's another key difference in Alienware's 15.4" model, though. While the 17" test unit contained an SLI set of graphics cards, the Area-51 m15x has only a single graphics card. Does the new configuration deliver enough horsepower to qualify as gaming-ready?"
