Really thay are almost identical when it comes to perfomance , one is better for 1-2FPD in a certain game and the other in another game by 1-2FPS .. really tbh get the 7870 you get free games with it, although if you dont want that and you want the 2.0 boost and physx then go with the 760
, but 7870 is the way to go in my opinion
