Ryzen 7 7700x or ryzen 5 7600x or the ryzen 7 5700x3d for Fortnite 240hz.

I am planning to upgrade my build so I can play Fortnite at 240hz, I am on the am4 platform, but I am ready to spend money and upgrade to am5, those are the CPU's that I am struggling to pick because the ryzen 7 5700x3d has the x3d cache or whatever it's called and people say it's really good for Fortnite 240hz, I need help picking one of those CPU's preferably the ryzen 7 5700x3d or the ryzen 5 7600x because the ryzen 7 7700x costs a lot. Thanks,
