If you haven't actually bought that GPU yet, the rule of thumb is spend roughly half your entire budget on it.

If this is strictly for gaming the 7800X3D is gonna give you more useful life than the 9700X because Zen 5% gains are fuck-all without VCache. See:

The Phantom Spirit is slightly better and cheaper than the Peerless Assassin:

If you can't name specific applications that you already know will use all 64GB of RAM then you don't need it and 32GB is fine. Anyway significantly cheaper same-spec kits:

Way overspending on that X870 board unless you know that one has specific features you need compared to something like this:

Overspending on the NVME when speed differences don't actually matter in low queue-depth client workloads:
