After a quiet summer season, Dell updated its flagship gaming laptop this morning. Replacing the XPS Gen 2 (a CNET Editors' Choice winner) and inaugurating Dell's new luxury line of laptops, the XPS M170 will feature Nvidia's new GeForce Go 7800 GTX graphics engine. At the moment, it is the only laptop to feature that GPU, though others, such as the Widow PC Sting 915, will follow suit in coming weeks.

GameSpot's James Yu breaks down the new Nvidia GPU: "The GeForce Go 7800 GTX, a 24-pixel pipeline chip based on Nvidia's GeForce 7800 GTX desktop GPU architecture, is roughly twice as powerful as the 12-pipe GeForce Go 6800 Ultra but has the same power draw to maintain battery life. The GeForce Go ships with a 400MHz clock speed and comes with 256MB of memory."

Aside from the new GPU, the XPS M170 is virtually identical to the previous XPS Gen 2 model. The Dell XPS M170 will be available online later today, starting at $2,699.
