Arc B570 pcie 3.0 x 8 vs 4.0 x 8

Hi guys, I have an Arc B570 paired with a Ryzen 5600g so currently the card is running at pcie 3.0 x 8, I was therefore thinking of switching to a 5600/5600x to take advantage of pcie 4.0.Do you think it's worth it? Will there be any significant differences? Thanks.
