There is certainly a good chance that it might be specially at higher resolutions

 

[feral64]

what can I do prevent it? can i overclock the cpu or should i upgrade?

 

[Nuckles_56]

you can do that assuming that you can overclock your CPU (which I can't remember if you can...) but regardless in the near future, you will have to upgrade your CPU

GeForce GTX 980 2 and 3-way SLI review

Of course, there's no way to gauge your bottleneck potential without mentioning your screen resolution. Lower resolutions, more dependence on the CPU and therefore more bottlenecking. Ultimately, you will be bound to bottleneck, as they noted in the above review with a setup considerably faster than yours.
