first of all no one plays with x4aa, simply turn that off and you're set, they turn that crap on just to bench cards because otherwise the cards would all look pretty much identical... no one plays with AAx4 on, no one. second even if you wanted to play at aax4, 40fps is good enough as long as the frames are well paced
You can afford to turn down graphic eyecandy a tiny bit to max out your system to 60fps in crysis 3. everyone does it. I still stand by the assertion the 7950/760 is all the gpu you'll ever need at 1080p.
as a sidenote, i will die a happy man if i can enter a convo about gpus and not get spammed by a techpowerup graph ever again. Their gpu ranking graphs are so far outside of every other benching site's results i can't believe people still quote them for gpu rankings as their results are clearly outliers for reasons i'm not quite sure. and that they seem to be quoted in every single gpu thread blows my mind.
the 770 is a nice gpu but it's about equal with a 7970GE (probably a little better, depending on overclocks involved), which is a card the 7950 well overclocked can come within an eyelash of matching... there is something massively wrong with techpowerups gpu graphs and i suspect the problem lay with driver issues. They do the same thing andtech does, which is mix driver versions in their graphs. for example, an older card will get tested on a game with the most recent driver when the game comes out, they save the result, then 4 months later they test a new card with even MORE recent and optimized drivers on that same game, then the new card benches significantly higher then the older cards because of a driver issue at the time the older cards were benched.
Those bench results from the techpowerup graph with the 760/770 are with drivers perfected for crysis over a number of months, while those of the older cards were of those cards when the game came out. as i said... while both are very nice gpus the 760/770 aren't significantly or even noticeably better then a 7950/7970GE respectively.
