+1 here, you can see throught walls.

I've got Intel i7 4770, SSD Samsung 840 pro with DayZ on, EVGA GTX980 ACX2.0 and 16GB ram.
Running DayZ in FHD (1920*1080), @ 144hz.

Putting everything at max except objects.
No blur, no ambient oclusion.

Objects very low in city > 40 fps
Objects very low outside city > 90 fps

Objects low in city > 35 fps
Objects low outside city > 90 fps

Objects normal in city > 32 fps
Objects normal outside city > 68 fps

Objects high in city > 28 fps
Objects high outside city > 45 fps

Objects very high in city > 22 fps or less
Objects very high outside city > 40 fps

GPU doesn't seem to be load 100%
CPU nevers goes up to 40%
DayZ eats like 2.8Gb ram.
SSD doesn't seem to be used.

Hope it helps.
