My Gigabyte G1 980 Ti not getting near FPS of Guru3d's 980 Ti?

Thanks,

So basically there's no point of using the of guru app since the "oc" mode is just a simple overclock that AB can do as well.

I see that you have a 980gtx g1 sli as well. Do you have the same problem as me that you don't have access to the modes since the synchronisation button is there instead?
