XFX GeForce 8800 GTS 320MB & 8800 GTX XXX Editions
XFX GeForce 8800 GTX XXX Edition
The XFX GeForce 8800 GTX XXX Edition ships in a similar looking box to the brand new 320MB GTS. Their bundles are similar as well, except for the fact that the GTX does not include a copy of Ghost Recon: Advanced Warfighter.

XFX's GeForce 8800 GTX XXX Edition is built upon a 10.5" long PCB, and the GPU and RAM are adorned with a massive dual-slot cooling apparatus. The more astute among you may notice the PCB on this card is green and not black like the first batch of GTX cards. The cooler is outfitted with a fan that is designed to draw air in from the back, and blow it across the heatsink's fins, where is it ultimately expelled from the system through vents in the case bracket. There are however, also some vents cut in the fan shroud towards the front of the card, which also aid in bringing temperatures down.

The 8800 GTX reference specifications call for a G80 GPU clocked at 575MHz with 768MB of RAM clocked at 1.8GHz. And due to the GTX's 384-bit memory bus, cards are equipped with 12, 32-bit DRAM chips, which all reside on the front side of the PCB. XFX's GeForce 8800 GTX XXX Edition, however, has its GPU clocked at 630MHz and its memory clocked at 2GHz. Those are some significant clock speed increases, which will give this card an advantage over stock models in terms of performance. The number of stream processors (128) and the memory bus width (384-bits) remain unchanged.

Other than its green color, another interesting aspect with regard to the GTX's PCB is that it has two SLI edge connectors along the top. NVIDIA hasn't disclosed any specific information about what the second SLI connector could be used for, but new SLI functionality is likely on the way.
The XFX GeForce 8800 GTX XXX Edition is also equipped with a pair of 6-Pin PCI Express power receptacles. Overall, NVIDIA has stated the 8800 GTX consumes a maximum of 185W (this card will be marginally higher), and the company recommends a 450W PSU that can supply 30A on its 12V rails.
