When NVIDIA launched their GT200 GPU and the first two graphics cards based on it - the GeForce GTX 280 and the GeForce GTX 260, they thought they had ATI licked for good. In fact, they originally pegged the GeForce 9800 GTX+ as the direct competitor to ATI's forthcoming (at that time) Radeon HD 4870 graphics card.

Unfortunately, NVIDIA grossly underestimated the ATI Radeon HD 4870, which not only roundly trounced both the GeForce 9800 GTX+ and the GeForce GTX 260, but was also more than a match for the GeForce GTX 280. ATI followed that up with a second blow - the dual-GPU Radeon HD 4870 X2, which effectively made ATI the new leader in the consumer 3D graphics market.
