PC builds are pretty much universal. They all use the same basic parts, to the point where you won't see a lot of difference until you start getting into custom parts or water cooling.
The downside is that you spent more on a CPU designed to be overclocked as well as a better cooler, which wasn't necessary for a PC user such as yourself. Overclocking is something that shortens the life of your components and can outright damage them if done improperly. Overclocking doesn't have universal rules where everything overclocks the same with the same results. What a particular part will overclock to is unique to that part, even between identical parts. Overclocking enthusiasts spend a lot of time tweaking their builds and settings to get the most out of their system, often time resorting to more advanced custom build techniques (water cooling, DIY mods, ect) to get their parts overclocked in the right way.
I don't suggest you try to overclock yourself (especially if putting together your own system is a new thing) as it is not guaranteed to produce the results you may have seen in some videos. Standard clock speeds are fine, especially if all you're doing is playing a couple games or browsing the internet.
