If you have a 13900k/4090 PC should you buy an Xbox?

Asking because I currently have a Spider Man 2 PS5 and haven't played the game and really losing interest in it now that I have my PC put together. However, Ive been wanting an Xbox for the backwards compatibility as some of those old games need extra work to run on PC (Prototype 1 for instance needs you to manually set affinity cores and also add a resolution mod to take advantage of GPU).

Is that overkill or do I have the correct combination currently?
