Hello GuJa,
Nice setup! No damage should be done to your components unless you go for a reckless overclock. Other than that, bottle necking doesn't seem like it should be a problem either, depending on what types of games you'll be playing.
Here's what I mean: To check your bottle necking, I used a website called Game Debate and checked it on two games. The first game is a less demanding one, Minecraft, in which the site said there should be no bottle necking.
However, when I looked at a newer title, Fallout 4, your CPU was reported as a bottle neck, but still powerful enough for playable FPS on ultra.
With those results, I wouldn't worry about it, because different titles are more taxing on certain pieces of hardware (as displayed in my bottle neck checker). Fallout 4 relies more heavily on your CPU, and Minecraft was more of an all round user.
None the less, your PC will run both games on playable FPS with ultra, but I can't give a number because those are only for premium users. As your parts become outdated, you can squeeze more life out of them with overclocking. Good luck, and feel free to ask more questions!
