Only you could answer that question by listening. I personally do not perceive enough difference between Cat 5 and theoretically better Ethernet wires, but ymmv.
Is it possible to place your System temporarily in the In the same room as the router and then try different Ethernet Cables to see if you can perceive a difference? It might be some work to move everything but not as much as the changes that you are contemplating, which may prove to be very disappointing upon completion
