There are a lot of factors involved when comparing your settings to someone elses, for instance what screen resolution and what cpu and is it overclocked, game settings, low, medium, high, antialiasing and that sort of thing.
If the core speed is boosting to 1442 that's a nice overclock.
If you're using a frames per second counter, try BF4 at stock settings with your 970, then try it with your overclock. You should see an increase, I would say maybe 5 - 10 frames per second.
Overclocking your cpu will give you an increase in frames per second too.
