I have an i5 4670k at 4.2 and an EVGA 970 FTW. I have just a couple of differences:
1080p
FXAA is my only AA
No reflection MSAA
Very High grass
High Detail Streaming While Flying off < may play with this one some more, during my initial benchmarks
someting was halfing my fps when it showed a lot of landscapes.
It practically never moves from 59 fps (due to weird 59hz refresh rate, but whatever). I did DSR down from 1440 for a while, but I went for the frames rather than the image quality.
I'm glad I managed to pretty much lock in 60fps (well, 59 haha)
