I keep having issues recording my games on my i5 6600k oc'd to 3.9 ghz (well aware it can go higher but overvolting isn't on my agenda). When i look up what people say about the i5's abilities in terms of recording and video editing, I keep seeing posts about how it can accomplish these tasks with ease, and that something like a 6800k is overkill, yet I'm having so much trouble using in a to record my footage. Is there a general overestimation of this processor's abilities? I've no enormous amount of experience in software, but when it can't achieve 720p 30fps on R6 Siege at a bitrate of 3000kb/s using a 264x encoder, something MUST be wrong with my pc, right?
The only thing wrong with your PC is probably that it has only 4 threads. There is a general overestimation of the performance of intel i5 CPUs. It stems from the era that they were the sole contenders in mid-range, that is not the case anymore.
The 6600k is OK for gaming, it has less smooth performance than the i7 because of its limited threads which cause more frame time variations, but it does alright overall. However, if you throw in anything other than "pure gaming on a clean install of windows", the Ryzen 1600 has a very noticeable advantage over the i5 lineup.
You might be able to use specific software and a fast SSD to improve recording performance, or you might be able to record with acceptable performance in some games. But if you want a consistently problem-free recording and streaming in every game, a 4 thread processor is not the tool for the job.
