Released on November 16, 2008, it is basically an XPS 730 with the new Intel Core i7 which also used the new Intel X58 Motherboards. The 730x, when configured with the Core i7 975 Extreme Edition, can be factory-overclocked to 3.73 GHz. 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 now supports a Tri-Channel of 6 GB of DDR3. The graphics card support is either a dual or single Geforce GTX 285, or a single ATI Radeon HD 4870 X2. The 730x operating system also supports 64-bit Windows. Dell has discontinued the XPS 730x in its US online store and is currently in the process of selling remaining stock. It has been mentioned that this was done to focus more attention for customers seeking gaming computers to Alienware.
