Hi. I found out about the whole custom GTA V multiplayer thingy this summer, I mostly did what Envious said. Just play on some medium-light RP server if that is what you wish to or any other depending on your interests.
I had hard time getting into the whole FiveRP thing because it was at the time very unstable and laggy on my PC, but now I’m getting a new one so hope it’d work out there better. Spec wise it’s gonna be lit compared to my old one.
