Hence why Im interested in switching from my FX-8120 to intel.
Keep what you've got. The FX-8120 is still pretty high end, it can't bottleneck a single GPU.
Switch to Intel you'll probably get the same frame rate, maybe a slight improvement like <5FPS average, I doubt any improvement noticeable to justify spending $500. Not sure how multi threaded Arma II is but you might even get less FPS.
Upgrade just the GPU. It's the only way to guarantee a FPS improvement in high double digits.
(also it's not the best time to be switching sockets. Piledriver is a few months away. It might be a quick and cheap upgrade solution if you decide to change the CPU alone)
