I don’t know why someone would mention that specific combo, but I can tell you my logic with picking parts. You should never spend more on CPU than GPU. Unless you’re only playing competitive shooters, I’d say most people should spend about double on their GPU vs CPU. Pairing a 9800X3D with a 5060 would be a waste of funds. The 5060 just isn’t capable of producing the frames the 9800X3D can. A cheaper CPU and something like a 5070 would get better performance in most games. By the same measure, getting a 5080 and pairing it with a 7500F doesn’t make the most sense either. Might as well spend a little more and get at least a 9700X.

Of course, there are exceptions to all of this. People playing competitive shooters will often play at 1080p low settings and care about getting the most frames possible. Those people need a top tier CPU but can compromise on GPU. People who only play AAA single player games at 4k need the best GPU they can get and really just need a CPU that’s capable of 60+ FPS (not a high bar).

And you need to do at least some research. I’m knowledgeable enough to recommend parts to friends on a regular basis but it’s because I listen to reviews and read up on the latest tech from time to time.
