It is quite understandable that AMD and NVIDIA slog it out in key price segments under $500, at price points wheregraphics card as a component competes in the market with gaming consoles. Almost every household has a PC with a PCI-Express slot these days, and consumers opt for a simple hardware upgrade by buying that graphics card to turn their MS Excel boxes into Games for Windows PCs. What happens at price points above $500? Pitched battles between the two GPU vendors for paper supremacy, even when no graphics card in the upper price points can really make volumes. For GPU vendors, having the fastest graphics card, like the Radeon HD 6990 in the market has two distinct advantages: the PR weapon of "we make the fastest in the market", and being able to capture the high-end PC and enthusiast markets. After its previous high-end graphics card, the Radeon HD 5970 got challenged by NVIDIA's GeForce GTX 580, which is unnoticeably slower, while being a lot more energy-efficient (since it's a single GPU graphics card). The red team just had to come up with something that makes up for that with a significant performance leadership over the GTX 580, so the 580's performance per watt advantage could be trumped with sheer performance.
