All that aside, this is what I got from the ARMA 3 FPS battle:
$200 FX-8350 Stock (4.0 GHz) @ 48 FPS
$360 4770K Stock (3.5 GHz) @ 49 FPS
$160 for 1 fps = Intel not worth it
$200 FX-8350 OC (4.5 GHz) @ 52 FPS
$360 4770K OC (4.5 GHz) @ 55 FPS
$160 for 3 fps = Intel not worth it
Oh, I just wanted to add that Intel's i7 line have integrated GPUs, while the AMD FX do not.
That being said, Intel's closest offering, Xeon, is significantly more expensive so it's not even worth looking at.
