GeForce Go 7900 GTX: For Hard Core Gamers on the Go

High-end laptop PCs for gamers are getting lighter, though they're still the behemoths of the mobile PC world. The original Dell XPS notebook weighed 9.25 pounds, was a full 2 inches thick and had a relatively puny 15.4-inch screen. The new Dell XPS M1710 weighs 8.8 pounds and has a 17-inch display. With power bricks, the difference becomes 11.4 lbs versus 10.6 pounds; the new power brick is a tad lighter, though it's all relative. It's progress, of sorts. The high-end version of the M1710 now ships with Nvidia's new GeForce Go 7900 GTX. Pretty much the same GPU as the desktop 7900 GTX, the mobile version is simply clocked lower and packaged differently.
