so i have a gtx 770 and im about to buy a new graphic card i will probably buy a zotac gtx 970 4gb but which is better? gtx 970 or gtx 780 ti? i saw many benchmarks where gtx 970 beats gtx 780 Ti with 2 or 3 more frame rates than the gtx 780 and yeah i know gtx 970 has a lower consumption, but for example will i get better fps with that gtx 970 or with gtx 780 in bf4?
