This isnt really an issue, but any discalmers and info about unlinking my ps account with my wt account?

i want to use the market place since i have things i can sell, but i have to unlink my account, i am planning to get a pc, but rn i have a laptop that can run it at 5-20 fps on low. Another reason is that it will give me a reason to grind event vehicles, although i am afraid i will regret this decision, and for that reason I want to ask you guys for any useful info.
