I've been searching online but cannot seem to find an answer to this question.
There is one scene in Hitman (Paris level) where my CPU usage is maxed out, and my GPU usage drops below 99%. I have a GTX 960 and a i5 3330 for reference.
To me that's a textbook definition of a CPU bottleneck, right? So in this scene, I get about 52fps.
Now, were I to play it with a GTX 1060 at the exact same settings and PC specs otherwise, will I still be stuck at 52fps in this particular scene?
Let's assume that this scene is bottlenecked by the CPU and not any other PC component.
I'm not fully clear as to what to expect and how CPU bottleneck works in this exact situation. I hope some experienced members of this forum can help me out.

You're asking us if you're going to not get 52fps in one particular scene? or if you will still be at 52fps in one particular scene? Not quite sure how we will be able to know that. With the 1060 being more powerful than the 960, I would expect to have some sort of improvement in the area. What kind of CPU do you have?

Just check your cpu usage while gaming. If your cpu usage is 80 percent+ most of the time then you are bottlenecked.

I don't know, why can't just I get a simple and direct answer?
At present, in Scene X, I get 52fps. There is a CPU bottleneck, cause CPU usage is maxed out while GPU usage is well below 99%.
Now, assuming the exact same settings are used and the exact same PC specs, when I switch the GPU from a GTX 960 to a GTX 1060 should I expect the framerate in Scene X to remain at 52fps, or should I expect it to increase? [Remember, Scene X is CPU limited]
Current Specs: i5 3330, GTX 1060, 8GB RAM, Win 10
I don't want general advice on CPU bottlenecking, I just want the specific situation/scenario above answered.

You might be capped that way, or the Pascal cards may be more efficient and get you a few more FPS. It's hard to know until you test it.

http://imgur.com/a/0Zz54 I've taken the CPU and GPU usages in there. The VRAM and system RAM are nowhere near fully utilized so those are not bottlenecks.

You have clearly answered your own question (see the bold). Therefore you should consider getting a more powerful CPU. Time to upgrade.

Agreed. A CPU upgrade will give you more performance

Push your I5 OC and answer your question, will a faster CPU help more than a new GPU
With good CPU & case cooling you can OC the I5 quite well

Yep.

If you're CPU is bottlenecking your 960, then running a faster GPU (1060) will also be waiting for the CPU just like the 960 is now. Except the amount of bottlenecking you see will likely be more frequent with the faster GPU.

You should see an increase. The reason is simple: per second, the cpu is spending some percentage of the time computing, and the gpu is spending some percentage of the time drawing. If you improve your gpu, it will spend less of the time drawing the same frames it had done before, which means there's time left over for more frames to be computed and drawn. You still might be cpu bottlenecked, but at a higher framerate.
