I5 4690k bottleneck sli

[comanv6]

Hello,my i5 4690k bottleneck the 970 sli on battlefield 1.why I tell this? Because whit the cpu overclocked to 4.2 my card's work at 70% having about 80 fps.
Then I push the cpu up to 4.6 and I reached 90% for the card's at 100/110 fps.
Will an i7 improve the results?

Battlefield 1 does benefit from more than 4 threads and is quite CPU heavy, so moving to an i7 would be beneficial for that particular game.

Yeah this is normal for BF1, it really benefits from an i7 especially in multiplayer.
