Nvidia confirms the GTX 580

[xdan]

So let's say altmost equal to 5970, consumes 10-15W more, and cost's 150-170$ less.
The price difference to 5870 is justified by performance.

GTX 580 as powerfull as HD5970, really ? Quite odd review

Why, 5970 was better 25-30% than GTX 480(in some situation). So GTX 580 is better with 17-20%(chip performance) + drivers= 25%.
Because Ati drivers didn't improve almost nothing, but Nvidia with 258.96...260.89, with 251.xx added 5-7% more performance.
