The HD 5970 is currently the pinnacle of gaming performance. It offers nearly unmatched in game frames-per-second in most new video titles, supports DX11, as well as Eyefinity, and has been AMD’s flagship graphics card for some time now. This is due to the card's dual 725MHz Cypress cores, which offer amazing gaming performance thanks to the 3200 combined unified shaders, 32ROPs and the 2GB of available GDDR5 memory. These specifications are impressive in and of themselves, but there are a handful of companies that won’t stop at good enough, and we can now add XFX to that list.XFX has just released its latest and greatest, and the company was nice enough to send us a sample. The graphics card is the XFX HD 5970 Black Edition Limited. If it sounds familiar there is a good reason. This card has become somewhat infamous for the alleged pre-release theft, eBay sale and the inclusion of a plastic P90 assault rifle. It does appear as if all of these have paid off though, as anticipation for this graphics card is high and there are very few gamers who have yet to hear about this XFX Black Edition Limited graphics card.What XFX has done with this graphics card is take the reference design and build upon it by adding 4GB of GDDR5 memory and dual Cypress GPUs clocked 125MHz faster than the reference models. This would be enough for most gamers, but the XFX card takes the 4GB HD 5970 in an entirely new direction. This is because the card uses six Mini-DisplayPorts to add support for up to six monitors using the ATI Eyefinity technology. This is intriguing to say the least, as who has not wondered how a HD 5970 (let alone a 4GB model) would run games spanning across six monitors?
