Advice needed

I am thinking of upgrading from an FX8120 to this http://www.overclockers.co.uk/showproduct.php?prodid=BU-012-GI&groupid=701&catid=6

My question is what kind of performance gains am I going to get in terms of gaming, I currently run a GTX 780 3GB, would it be better to upgrade the video card instead?. Any help would be greatly appreciated.

I am getting told a lot that my CPU will be bottle necking my GPU, I usually get about 75 percent GPU usage so I assume that's correct and with CPU intensive games like GTA V coming out I reckon I will need a much better CPU than the one I have. I am getting around 50 fps on farcry 4 on high and some very high settings.
