Arma 3 preformance

[tom20r2]

amd fx-8320
xfx r9 280x
8gb ram

I really want to build a pc and arma 3 is one of the main games i want to play. Someone please tell me what kind of preformance i will get using this rig and if there is anything i could change with the specs.

Thanks

if you are playing at 1680x1050, not 1920x1080 (1080p), you should max the game. If you meant 1080p, you should still probably max it.
