The Dell Dimension XPS series is the company's answer to the high-end boutique systems from builders like Alienware, Falcon Northwest, and VoodooPC. Though the XPS isn't obscenely overclocked like its boutique brethren, it is wickedly fast and pretty distinctive in its own right. And this time around, it's equipped with a new processor: In fact, the Dimension XPS Gen 5 ($3,999 direct with monitor using Dell e-value code 6V411-XPS5PC) is the first system we've seen with the dual-core Pentium Extreme Edition 840 (Pentium EE 840) processor. (Read "Test-Driving the Dual Core Pentium EE 840" for more on what dual-core processing means for your computing experience.) With the addition of Microsoft Windows XP Media Center 2005, the XPS Gen 5 is more than just a gaming system, it's Dell's top-of-the-line gaming/multimedia machine and our latest Editors' Choice.
