i hope some of that is true but if you trully believe the r600 will just 'blow away' the g80 then i think you might be mistaken. I have always though that it will be better, but trusting an article that is 'speculating' that it will be twice as good as the g80 is ridiculous. And most of that is speculating.
The R600 HAS to be better than the g80s. Why would the r600s release months after the g80s and have less performance. IF the R600 is worse, we will see some delays.
