I would really wish some other site were able to confirm or deny these findings. I stopped reading TTR after reading their stupid article about AMD censoring material and the original 660 ti review due to their blatant bias. They use a different method to test cards/cpus which is good but their numbers are often times inconsistent with everyone else. The review themselves are just written as best of they can to down play any AMD cards and even to exclude any test that would showed AMD winning.
I wouldn't actually be surprised if TTR just randomly made up the graphs at this point because of how they insist on doing the same articles to make nvidia look better at this point and using data that not only is selected based on favoritism but also inconsistent with other sites, they only hide behind their testing method at this point.
First it was the original 660ti review where they included TWIMTBP games where AMD suffered in the final conclusion but removed gaming evolved titles where nvidia suffered. Then the update which they hid behind windows 8 drivers and a selection of games that were different, Removing BF3 and other AMD favored titles and adding a few of TWIMTBP titles. The conclusion was stupid and the testing was stupid so when they were called out, The made the follow up review which at this point I am not even inclined to believe the numbers.
The whole year of review from the tech report has been praising nvidia. Thats not so bad but when they often skew the price of AMD and nvidia cards in the conclusion and not including AMD favored results. It starts to be something.
