It runs fine on my AMD 4170 @4.2hgz with a lesser gfx card (GTX660) so you should be fine, here it is at medium setting (a couple of setting on high) 2x AA. Motion Blur/Fur/Ambient Occlusion/Tree Relief are Off.

Runs 40-45fps climbing 55-60 in some parts, could be better if I lower the settings a little more but plays fine like this for me
I expect you will get better as you have stronger GPU.
This should be enough for you to play in high/very high settings in 1080p without any issue... BUT
this game stutters A LOT (even though you match the recommended specs) unless you have an alien machine
