I Want MORE power !

Solution


A new motherboard (Z97) and CPU that is a "k" model would allow you to overclock the new CPU. That might give you a performance boost, but you need to identify if the CPU is a limiting factor.
Run your game, when you see the FPS drop, watch what the CPU and GPU loads are. If one is at 100% or close and the other still has performance left, there is your bottleneck...if you have one.

If you want more power, get a i5-4670k or a i7 4790k, a new motherboard and overclock. Or you could get another 980ti and SLI them.
