Wizzard, you should use Cat 13.10b on 7990 to achieve her frame-pacing feature and deliver more consistent FPS results(on average maybe will be only a little better, but results can become better on many games).
The TPU test is the most fair(and the most objective) on web, but i think results is favoring a little the Nvidia cards due to the selection of games(and AMD's driver team lack of competition spirit). You could exclude from the test the less demanding games(Like diablo 3 and the CoJ)(That are a couple of games that the $400 GPUs are maxing out in Surround Settings!) to make the test more equilibrated.
Total War: Rome 2 can substitute Starcraft HoS;
Battlefield 4 could substitute CoJ;
Splinter Cell Blacklist and the Batman Arkham Origins can enter in the test;
Arma III can substitute CoD(but i understand CoD importance in the test);
Guild Wars 2 can subtitute World of Warcarft;
Saints Row 4 can substitute Sleeping Dogs now and Hitman can be substituted by the New Xcom;
Need For Speed Most Wanted is more(by the rate of 1,65x/1) demanding(and more fair) than Grid(That uses AGE coded Lighting effects);
Metro 2033 can go back to the test as it still can be hard to max out on most of high end systems like Crysis 1 still does today.
Diablo 3 can be subtituted with Witcher 2 Enhanced Edition that still is hard to max out nowdays(Disable supersampling to not favor AMD cards on the test!)
And are you planning to show 99% FPS of the cards in the test someday? (Well, this is the only of the new meters i like...)
