It has nearly been five months since AMD first introduced its DX11-capable graphics cards starting with the AMD Radeon HD 5870 powerhouse that has been followed by the HD 5850, HD 5770 and HD 5750. And even though there are very few titles available today (or even set for a Q1 launch) that will take advantage of DX11, you can be sure that NVIDIA and its investors are paying attention to how far behind the other GPU giant is falling. With Fermi and GF100 (the consumer card design based on Fermi) set for a March release time frame, that would in theory give AMD a solid 6-7 month lead. What they are able to do with that lead depends greatly on selling as many GPUs as possible between now and then to cement ATI's position as the leading GPU technology for the coming years.
