I recently got passed down a EVGA 980ti SC; I am concerned with one thing. I was getting better FPS with my previous card HD7850 which shouldn't be the case 
Listed below is my rig as of now:
Mobo: GIGABYTE 970A-UD3P
CPU: AMD 8350
RAM: 16GB corsair vengeance pro
GPU: EVGA 980ti SC
PSU: EVGA 650W G1
Any help would be greatly appreciated as I would like to get to the bottom of this.
Kind regards.
