AMD has enjoyed a terrific run with the Radeon HD 5000 series as it took Nvidia no less than six months to counter with its initial Fermi products. It's been a year since we reviewed the Radeon HD 5870, calling it a "real winner, and possibly one the best graphics cards we have ever reviewed in this price point." Within five months of releasing its first DirectX 11 GPU, AMD launched another eleven graphics cards ranging from affordable to the ultra-expensive.On the other side of the fence, the GeForce GTX 480 and GTX 470 arrived months later and weren't nearly as well accepted as Nvidia hoped. Some two months after entering the DirectX 11 market, Nvidia tried to crank up the heat by unleashing its GeForce GTX 465. Sadly, the card was a flop and it took them six more weeks to finally make headway in the DX11 GPU market with its GeForce GTX 460.
