Is my hardware bottlenecking?

[SvediZZ]

I've noticed that my system might be bottlenecking in a couple of games, these are Mafia 2 (after you've got out of prison) and World of Warcraft (patch 7.0). In certain places on WoW my GPU usage drops to about 50-80% and in Mafia 2 to around 80%, this gives me quite the framerate drop. The thing is, it doesn't happen in every game, it's just in this two I've noticed the problem. Also, running a GTX 1070 with 2100MHz core clock and 4392MHz memory clock with an i5-4690K overclocked to 4,6GHz with 1.275vcore, I don't believe that my CPU is bottlenecking my GPU because it's way too strong. I also forgot to mention that my CPU usage drops simultaneously with the GPU usage, so it's not like my CPU is at 100% and my GPU is at 60%.

And your temps when this happens? It tends to Throttle above 60C or so I've heard.

Well, my CPU temps are around 60c when gaming and my GPU is at about 70-73c with my custom fan profile (stock was at 82c). Also, I think it's worth mentioning that my GPU usage is always at 0% no matter what I do.

I disabled kboost which was making my GPU show 0% usage. Now I'm getting like 80-90% cpu usage and around 50-60% GPU usage in Need For Speed. I saw a benchmarking video with the same GPU as me but with a 6700K at 4,6GHz, and that guy had like 130fps where I had around 70. This appears to be a bottleneck but I think it's very weird for a 4,6GHz 4690K to bottleneck a GTX 1070.

Also, I didn't have these bottlenecking issues a couple of days ago (exact same setup).

Check your system for any malware.WoW side, make sure your add-ons are up to date. A system doesn't just magically start to bottleneck.
