Dell XPS 720 H2C
Dell gets it right this time around in many other ways. The sealed liquid cooling system was developed by CoolIT Systems especially for the XPS. The memory used is Corsair XMS2 DDR2-800 memory. Although it's only DDR2-800, it's not generic DDR2-667, as we've seen in past XPS gaming rig. Dell also builds in a pair of GeForce 8800 Ultra graphics cards, a custom X-Fi sound card with digital optical ports and an Ageia PhysX physics accelerator card. Dell wraps a massive, glossy black steel XPS chassis around this hardware goodness and powers it with a kilowatt PSU. Dell will be offering an Intel quad-core QX6800 CPU overclocked to 3.46GHz, but you can also buy it running at the stock 2.93GHz.
