Today Nvidia announced that its GeForce 8800M GTX graphics could be combined in an SLI configuration. The scalable link interface lets two graphics cards work in tandem, essentially doubling your graphics capability for added performance on the most hardware-demanding games. The concept is nothing new, of course, and we've tested several laptops, such as the Dell XPS M1730 and Alienware Area 51 m9750, running earlier Nvidia cards in SLI configurations. Today's announcement just marks the SLI compatibility of Nvidia's latest high-end laptop GPUs.
At this point dual GeForce 8800M GTX configurations haven't shown up on manufacturers' Web sites, but Nvidia tells us we can expect gaming laptops from Dell, Alienware, and others to incorporate the technology "soon."
