i said this back when the GTX 670 was released on May 10th in the Conclusion http://alienbabeltech.com/main/?p=29607&all=1
For its $399 price, it gives more than 90% of the performance of the GTX 680 which is priced at $500 and the 570 comes right into the $480 HD 7970′s performance territory. For the second time, the reference HD 7970′s $480 price needs to be adjusted downward. In this way, the GTX 570 is a game changer.
If AMD had met the GTX 670 with *today's* pricing when it launched 9 weeks ago, i think the public perception of Kepler vs. Tahiti would be different.
AMD is way too slow to respond and their strategy is traditional and too predictable to be effective.
-- if *I* can call it right weeks or months in advance, then AMD is in deep trouble as "strategists"
