The Dell XPS M1730 is just over 10lbs of serious power.  It has a 17″ 1920×1200 LCD, SLI, PhysX, it can handle RAID 0 or 1 as well as up to 4Gb of DDR2 800.  All in all it is serious competition for the Alienware m9750 that Ryan tested recently.  Check out the current pinnacle of laptop performance at AnandTech.

“We looked at WidowPC’s Sting 512D2 a couple months ago, and the XPS M1730 is a case of one-upmanship in pretty much every way. A single 8800M GTX is very fast when it comes to mobile graphics performance… so why not have two paired together in SLI? Core 2 Duo T7600 is a fast mobile CPU, but how about increasing the clock speed and cache a bit more and moving to Intel’s latest Penryn architecture, courtesy of the overclockable X9000? You can also get two hard drives in RAID 0 (or RAID 1 if you prefer data integrity to performance), a brighter LCD, a better keyboard layout, and a few miscellaneous odds and ends like the configurable glowing LEDs that light up the chassis.”
