Lol!
Performance summary-2- includes Starcraft and WoW! They merely removed the more broken games.
Honestly... Two extremes right there. You and the quotee.
Not sure if you understand ENGLISH?
"This affected the performance summary results on the previous page, which is why I decided to create another set of graphs without the following games: Assassin's Creed 3, Batman Arkham City, F1 2012, StarCraft II, Skyrim, and World of Warcraft."
Also, if me pointing out the obvious: useless to bench low resolutions with top end gpus, and that cpu limited games also removes scaling to make multigpu solutions look worse somehow makes me extreme, then you are probably too blinded by your green nv faith to see logic.
Edit: For clarity sakes, the summary 2 puts 7990 very close to a gtx690. Given the choice, for gaming reasons, it would be complete silliness to pick the 7990 over a 690. Similar performance for much more power use is a lose scenario. As for the "normal" summary, its completely useless since it includes games where the 690 looks horrible in comparison to single gpus as well, aka, bottlenecked titles. As several have pointed out, 2x 7950 for cheap and manually OCed with a profile for radeon pro (until AMD's "smooth" drivers) = best damn bang for buck this gen and prolly well into next gen.
