How much will the performance increase with 4770k OC?

How much will the performance increase from 3.5 Ghz to 4.6 GHz with the 4770k?

Quite a lot I bet, but why do you want to overclock this monster anyway?

Since I have a Nh-d14 fan on a non-OverClocked cpu.

So I thought; Why don't I OC?

In games you will get a 5-15% gain in fps, which is very useful to avoid problems with sli or the difference between laggy game and smooth game if you have spent al the money in CPU and the cooler. Notice also that AMD cards are more cpu dependant than Nvidia's.

In productivity, video encoding and that kinda things there will be much more improvements, with 4,5ghz I remember reading a review that conclude in a 28+/-2% better performance.

Remember also that power consume will also be increased and the life of the cpu will be shorter. If you don't have lag issues or you don't use programs like Photoshop or 300 pages words/PDF/whatever I would recommend a lower speed, 4,3-4,4 is also great and also overkill.

I also have a 4770K, but only OCed to 4ghz, and only because it sounds way better than 3,9, and I can open a 120MB Excel in 15-17 seconds, a 25% increase would put that to 12-14, just 3 seconds you can spend jumping to be in better shape.
I suggest ocing it in 4 years time, ocing it now will only degrade the cpu, and in 2018 cpu world has to change a lot if a 4,6GHZ 4770K isn´t better than the stock 6770K or dshjgfka834 or whatever name they think it's "cooler".

The performance increase will probably be noticable depending on what you are doing. Higher clocks mean things get done faster. FPS will increase a bit in games.

However, chances of your 4770K hitting 4.6GHz are a toss up. Even with a good cooler, the Hasewell chips seem to have an OC wall depending on your chips batch. Some will do 4.6,4.7,4.8GHz and others won't get out of the low 4GHz. I am stuck at 4.3GHz and can not get 4.4 completely stable for the life of me. Still, that is nothing to be ashamed of and compared to the stock 3.5GHz it still performs better.

at 3697 Mhz, the temps never exceed 50 degrees Celsius. Is there a way to tell how much I can OC without trying?

How do I know if it's stable?

I started out going right to 4GHz and creeping up 100MHz from there. I run OCCT and do the CPU stress test for maybe 20 minutes. I also run AIDA64 as well. If it lasts that long you are probably at a clock you can get 100% stable. If it runs 20 minutes I move up. I got 4.4Ghz stable on a 20 minute run, but it was randomly crash in games and such. I tried everything in the world to get it stable and nothing. 4.3 is rock solid. I had to fiddle with the voltage a bit. Just make sure you use a fixed voltage to find the stable voltage. Then you can switch it to adaptive if you want to make sure it ramps down during low utilization. Adaptive can fluctuate the actual max voltage so to find your stable clock and voltage work with it fixed at first.

AIDA64 will heat things up to about 80C-low 80C. In games like BF3 or Tomb Raider I see up to maybe 70C. Idle I'm at around 28-30C.

So the CPU is stable when the games/programs doesn't crash?

I typically run some stress tests like OCCT or AIDA64. If it runs fine for a length of time you are usually good. However, I've had times where I've run into issues after a hour or two of gaming. In those cases I may increase the voltage slightly or clock it down.
