No, do a search of Theinquirer before the R770 lanch, he said the R770 would be much faster than G200 and the R700 even more so. And if memory serves correctly, Nvidia didn't demo a thing prior to G80 launching either so that isn't anything to go on. Charlie just simply sucks at predicting Nvidia launches.
"Last year, the mere suggestion of ATI doing well was laughed at, but the firm took the outright lead with the X2 cards and forced NV into the reactionary GX2. ATI can do three and four-way adequately, albeit with the the Broken OS, while NV can only do it in name. Same with the bucket called 'hybrid' for both power and frame rate.
ATI has been plotting a comeback, and the R770/R700 parts should take the outright lead once again. The trick to the cards is what we told you almost two years ago"

Says R770/R700 should take outright performance lead, only r700 did that. He also claims TRi and Quad SLi to be broken which was and still is also pure BS.
