The XPS 17 3D reviewed here ships with an Intel Core i7 2820QM clocking in at 2.30GHz but capable of pushing to a full 3.4GHz in Turbo Boost mode. This is one of Intel's latest quad-core processors built on the new architecture's 32nm manufacturing process. It's a major improvement over past Intel quad-core mobile CPUs, offering faster clocks, more robust power management, and overall better performance.

The display provides the 120Hz refresh rate and IR emitter necessary for stereoscopic 3D. We used it with an aftermarket set of Nvidia's 3DVision glasses, and everything works quite well. Driving the display is an Nvidia GeForce GT 555M mobile GPU. Dell has beefed up the resolution of the display to true 1080p.

Most of the other features are comparable to those of the earlier XPS 17, including dual hard drives, four USB ports (the two on the rear are USB 3.0 capable), 802.11n, a Blu-ray drive, and both HDMI and mini-DisplayPort digital video output connectors.

Our test system's performance in standard desktop apps was stellar, producing one of the highest scores we've seen from a laptop on , an impressive mark of 151. The new Intel CPU, coupled with a staggering 16GB of main memory, were no doubt major factors. You'll pay for this power, however: The XPS 17 3D starts at $1450, and the configuration we reviewed will run you $2389 (prices as of February 2, 2011).

The Nvidia GT 555M is newer than the 445M that Dell used in the last-generation . Since the screen is now true 1080p, however, the 555M needs to drive 44 percent more pixels than the older laptop's 1600 by 900 display had. That means lower frame rates in games, so you may want to dial down the resolution a bit if you're playing current-generation titles. The performance of the GT 555M seems only slightly better, as in 3D Mark 2011 this laptop garnered a score of 1307 versus the mark of 1286 from the older XPS 17.
