The H2C edition computer has included a dual-stage radiator cooling technology, and a motherboard capable of overclocking its quad core Intel Core 2 Extreme QX6800. The H2C comes standard with dual nVidia GeForce 8800GTX cards running in SLI at a price of $6,780. The XPS 720 H2C uses slightly higher quality parts than the other XPS classes and is currently one of the most powerful and one of the fastest pre-built systems that an individual can purchase by a significant margin. Hampering its overall performance however, are the locations of the PCIe 16x slots. In an ideal SLI configuration, the 16x slots must be close enou the second 16x is at the far edge of the board. This is now not available in the United Kingdom. In the United States, the XPS 720 H2C is only available through Dell Outlet now, meaning no new computers of this model are being manufactured.
