FUD Zilla heard AMD's upcoming Cayman GPU may be the new R300:
If you are old enough you will remember the famous Half life 2 vouchers and ATI’s first leader series, which included the now legendary Radeon 9700. This chip dominated against Nvidia's Geforce FX 5800, the infamous NV30, so Cayman has a lot to live up to. This was some eight years ago, in summer of 2002, way before Tweeter, Facetube and Youbook launched.
AMD is either hoping that Nvidia doesn't have a chance with its GF110 aka GTX 580 or that Nvidia could fail again. However, we believe that making the same mistake twice would be something that would really upset Nvidia CEO Jensen Huang.
