Hi. I want to get a new Gaming PC. But I'm not sure if I should get an Ryzen 7 3700x or an 3900x. I know that Games don't use that much CPU Power, but I don't know how it is in 4k gaming. And although there are games like GTA 5 that need a lot of CPU power. So I'm asking you for your experiences or knownledge in this Topic. *(I'm very sorry if I typed some mistakes in this text. I am not english so sorry for this.)
