Much depends on the game and engine. I'll dabble in Neverwinter every now and then, it's not much more demanding than minecraft so my gtx970/i7-3770K is well capable of max ultra beyond 60fps, I use MXAA x4 on it as anything higher makes characters look so soft they start blending into the background. X4 keeps some rigidity to the face at least. FXAA is older than MXAA and isn't well optimized for much, it tends to get quite cpu intensive for not much gain, but some ppl like it. Same goes with plain AA or AF (antistropic filter) it can be just enough, but having it at max isn't always a good thing.
There's other settings too that can be detrimental to fps, like grass detail and viewing distance. As fast as you drive by in gta:v, you...
