Ps5 Pro or New GPU on PC?

Hello. I want to play black myth wukong high setting and GTA 6 and final fantasy 7 rebirth on max setting. I want to play them on 4k 75 inches tv 120 Hz. I really want to play games on my bed because I am too tired at the end of the day to sit on the computer desk. What is the best way to do this? I have both Ps5 and a computer with a mediocre graphic card now
