NVIDIA rolled out a new module to enable GeForce 8800M GTX SLI on notebooks:
Then again, they don't quite have the same specifications as their desktop counterparts, and there are folks out there looking for a laptop that'll let them play Assassin's Creed when it comes out. Presumably in an effort to satisfy that particular demographic, Nvidia has announced that notebooks with dual GeForce 8800M graphics processors running in SLI mode are on their way. Alienware, Dell, Sager, Eurocom, MALIBAL, Cybersystem, Multirama, Nexoc, and Rock have all worked with Nvidia to squeeze two GeForce 8800M GTX chips into their high-end gaming laptops, and the first systems should be available "soon."
One of those systems is Dell's XPS M1730, which accommodates only dual GeForce 8700Ms right now but will be updated to support dual 8800M GTXs. In its top configuration, the machine currently delivers a 2.8GHz Core 2 Extreme X7900 processor from Intel, 2GB of DDR2-667 RAM, two 200GB hard drives running in RAID mode, a DVD burner, a mobile Ageia PhysX processor, built-in Creative SoundBlaster Audigy HD audio, 802.11n Wi-Fi, and a nine-cell battery. Weight starts at 10.6 lbs (4.81 kg), and Dell charges $4,438 for the machine. We'd expect dual 8800M GTXs to raise the price tag a little, though.
