As is usually the case when you slap the latest and greatest silicon in a laptop, it's going to best whatever came before. What's surprising here is how thoroughly the Dell XPS M1730 with a Core 2 Extreme X9000 processor and dual GeForce 8800M GTX cards in SLI trounces the last generation of tech. The folks at ExtremeTech pitted the laptop against a hapless m9750 from Alienware, sporting the last generation of tech, and it handily bested it in every competition. CPU tests were heavily in the M1730's favor, and GPU tests even more so. The only holdup is that new X9000 processor, and according to Dell a release is "imminent" -- and if you're shelling out $4480 for a laptop, it might as well be what ExtremeTech calls "the fastest notebook yet."
