Ok so I don't get amazing FPS in games. In the crisis 3 Beta I get around 40 FPS with graphics on the lowest, and it makes no difference how high or low they are. This is what makes me think it's the CPU. Will I get a HUGE FPS increase by Upgrading to the Intel 3770K ?
And is my CPU bottle necking my GPU ?

Upgrading your CPU will give you same on highest settings but increase fps on low settings. For gaming you would get the same results with I5 3570K as the I7. I personally would not bother.
I say stay where you are. It may not be as fast, but for games you won't notice a whole lot of difference. I am pretty sure it should not bottleneck you gpu.
Instead of spending $300+ on a new board and CPU, how about $50-75 on a killer cooler and take the 8120 up to 4.5-5Ghz?
