You may want to take a closer look at that benchmark again. In BF4 the 780ti scores higher than the 290x in average fps. Considering the test scores the minimum, that means the maximum is higher still than the 290x. Either way, only the minimum is rated there and that counts for little as its only in one instance it hit that low. 780ti is better overall.
The only 2 cards that actually beat the 780ti in average fps were dual gpu's. A lil unfair to test a single gpu up against xfire, but even so, they only barely beat it. you could put sli gtx 770's up against a gtx690 or hd7990 and the 770's would trounce either card, and quite handily.
I'm not ready to concede that based on 1 biased benchmark that ppl should not go nvidea. That test is also not recent. November of last year, on a 3570k. You base your opinion on
1 game, and I don't even play it. i'll stick with NVidia thanks, haven't had driver problems, no waiting for mantle, no bug fixes, no working on it, no bluescreens etc etc etc....
The other benchmarks put the Best AMD vrs the 2nd-best NVidia, 290x vrs 780, and then claim 'oh, AMD is better!" I wonder what those benchmarks would say if they put the best NVidia vrs the 2nd-best AMD... a 780ti vrs a 290... 'oh, NVidia is better!'
Like I said, biased benchmark... basically a bunch of BS
