I am not an expert. Today I installed the Ryzen 5700x with a "be quiet! Pure Rock 2". I found the price/performance ratio to be excellent and installation was straightforward. It's important to pay attention to the height so that the cooler fits into the case. I have not yet been able to test it under load. I will add four additional fans to the Air Flow in the case and then get started.

Different games have different requirements, it's best to read the recommended game requirements. Sorry but it's the best I can do.
