In addition to announcing its new Streak 7 tablet, Dell has taken the wraps off a pair of notebooks and desktops with Intel's new processors. Besides the new Core i3, i5 and i7 options, the revamped XPS 17 has also received Nvidia's 500M series GPUs with support for Optimus and 3D Vision when configured with an optional 3D display. WiDi with support for 1080p streaming is also on the menu if the system is outfitted with a quad-core i7 processor.

Along with the new i5 and i7 chips, Dell has added an HDMI input on the Alienware M17x rev 3, so you can connect a Blu-ray player or gaming console. New graphics options include the 1.5GB Nvidia GTX 460M, 1GB ATI Mobility Radeon HD 6870M, and the 2GB Radeon HD 6970M. Like the XPS 17, the company mentioned a 120Hz display, so we assume Nvidia's 3D Vision technology is supported if the machine is coupled with a GTX 460M.

Meanwhile, the Alienware Aurora and XPS 8300 have also been treated to Sandy Bridge chips, and the former will have options for overclocked CPUs, liquid cooling, CrossFire and SLI dual-GPUs, as well as new matte black and dark chrome finishes. The M17x, Aurora, and XPS 8300 will be available as of January 10 for starting prices of $1,499, $1,799, and $749, while the XPS 17 won't begin shipping until February 1 with base pricing set at $1,449.
