Dell has raised the performance bar once again with the launch of the XPS 730 H2C edition, a premier gaming desktop that Dell says is "one of the most advanced gaming platforms on the planet". Available in two models - air-cooled XPS 730 (starting at $3,999) and water-cooled XPS 730 H2C (starting at $4,999) - both systems offer the new NVIDIA nForce 790i Ultra SLI chipset, optional factory-overclocked Intel Core 2 Extreme processor, Corsair DOMINATORTM DDR3 memory and up to four hard drives in RAID array. Graphics options include the ATI Radeon HD 3870 X2 in four-way CrossFireX or NVIDIA GeForce 8800GT in SLI. All this is sold in a 2.4mm anodized aluminum chassis available in Victory Red and Stealth Blue or brushed aluminum in Silver on the air-cooled XPS 730. Each case comes with a 1kW 80PLUS power supply and can be configured with an optional X-View clear side panel. The water-cooled version of XPS 730 is also enhanced. Originally co-developed by Dell, Intel, Delphi and CoolIT, it now features redesigned CPU coldplate, added block for the chipset, dynamic speed control for the pump and fans and a separate fan for the CPU's voltage regulator components.
