Dell XPS 730 H2C

The Dell XPS 730 H2C is Dell's highest-performing consumer PC ever. It comes with the usual gaming rig accoutrements: lighted windowed case, hulking chassis, overclocked quad-core processor, latest technology, and dual-card graphics. Since each ATI Radeon HD 3870 X2 card has two GPUs on it, this is really a quad-GPU gaming leviathan. At this price level, however, only high-end gamers with deep pockets need apply. It yielded some of the better gaming performance I've seen lately, but for the time being you're really buying a system with future-proofing built in. You can get this thing for $6,629 direct.
