QX9770 up to 3.64 GHz. Dual channel DDR3 SDRAM system memory was available in United States and UK. There was a choice of colors also at some outlets. The basic model specs of the PC were: Intel Core 2 Extreme Processor QX9650 (3.46 GHz Overclocked), DUAL 1 GiB ATI Radeon 3870 X2 Crossfire X Graphics Card, 2 GiB Memory, 1 TB 7200rpm Dual HDD. The base price in the UK was £2,499. The system also came with an improved H2C cooling device, seen on ultra high gaming computers. This has since been replaced by the XPS 730x (see above). XPS 730X, XPS 730X H2C Released on November 16, 2008, the XPS 730X is essentially an XPS 730 with the new Intel Core i7 which also used the new Intel X58 chipset Motherboards. The XPS 730X H2C was the higher-end version of the 730X that made use of H2Ceramic cooling and often shipped with factory-overclocked Core i7 Extreme Edition processors. The 730X also integrates Alienware's AlienFX and a new theatre lighting system. The internals of the 730X have also been redone for ease of upgrades, although most of the inside remains the same. The 730X supported a Tri-Channel of 6 GB of DDR3. The graphics card support was either a dual or single NVIDIA Geforce GTX 285, or a single ATI Radeon HD 4870 X2. The 730X originally shipped with Windows Vista, but eventually offered Windows 7 near the end of its availability. Dell internally discontinued the XPS 730X and XPS 730X H2C in its US online store on August 1, 2009 and cancelled any remaining orders after August 15, 2009. It has been mentioned that this was done to focus more attention for customers seeking gaming computers, such as Alienware. The desktop was officially discontinued on September 17, 2009 (see Dell XPS 730x). Laptops Dell returned to develop their XPS performance line. The three new laptops, released in October 2010, have many new features and specifications from the old models. They feature JBL speakers with Waves MaxxAudio 3 technology, and have integrated 3D graphics. The line is the first to be Skype-certified for video chat. They have Intel i5 and i7 processors. The X-Fi upgrade offered by Dell is not actually a hardware upgrade but a software-based processing package which "provides premium audio quality, effects and features".
