Nvidia's top end GeForce GTX 260 and 280 graphics cards-whose power borders on sorcery-launched for $399 and $650, respectively, less than a month ago. But pressure from ATI has driven Nvidia to already cut the price, hard. The GTX 280 is now only $399, while the GTX 260 is $299, the same price as ATI's HD 4870. Good to see ATI back in the fight. Anyone already buy this and feel hosed though? Competition is a lovely thing. [CNET]
