Question Motherboard for 9800X3D - X670E vs. X870E for Future Proofing

[Blue0]

Salutations! I seek the wisdom of the tech council.

I'm planning to buy the 9800X3D and I'm trying to pick a good motherboard for it. From what I've researched, for future-proofing, I should probably go with either the older X670E or the newer X870E, mainly because they both have a lot of PCIe Gen 5 lanes and plenty of USB slots.

I don't have a Gen 5 SSD yet, but I do have a graphics card that supports Gen 5, and I'd like to make sure I won't need a new motherboard for at least the next 10 years if possible.

I want enough PCIe Gen 5 lanes to support my GPU and eventually two Gen 5 M.2 SSDs. From what I understand, that means I'd need:

16 lanes for the GPU (Gen 5)
2 x 4 lanes for the SSDs (Gen 5)
So, a total of 24 lanes. But some people are saying that the X670E doesn't perform as well as the X870E, while others say that the X870E actually uses 4 PCIe Gen 5 instead of Gen 4 lanes for USB, so there might not actually be 24 lanes available for what I want.

I'd also prefer a motherboard with built-in Bluetooth and Wi-Fi. Does anyone know if having built-in Bluetooth/Wi-Fi affects the availability of PCIe Gen 5 lanes?

I'd really appreciate it if someone could clear this up. Does the X670E actually fall short in performance? And is it true that the X870E doesn't have enough lanes because of USB or other built-in features? Any insights would be super helpful!

Depending on the money you give, you will also choose the motherboard.You can find an 870E and for the same money there is a much better 670E.The choice is purely yours

It's not about performance but equipment options of the chipset, that's only difference between 600 and 800 series MBs. As long as MB is capable of supplying enough power to your chosen CPU performance difference between lowest and highest MB is at ~1% margin.

Thank you both for your answers!

Just to confirm.
Based on what you said, in my case either motherboard should be fine. The difference between the X670E and X870E is mainly that the X870E has USB4, correct?
And both have the full 24 PCIe 5.0 lanes available for use, with built-in features like Bluetooth/Wi-Fi and the USB4 in X870E not affecting that?

If that's the case, it seems like the X670E would be the better option for me due to the lower price and me most likely not needing the USB4 in the next 10 years.

USB4 and more and newer version of PCIe lanes (which may include M.2 ports) from CHIPSET. From CPU stays same as that depends on CPU itself.. Even built in WiFi/BT use one PCIe lane usually from chipset.
So yeah, CPU/RAM/GPU wise x670 and even b650 (for up to 12 cores) would be exactly same. For9800x3D a good and relatively "rich" (like mine) MB would be quite and more than enough. If it can produce great results with 7900x that consumes more power (up to 170W) it has more leeway (up to 180w) even for some OC. as it requires less
Ps.
Yes it has adjustable BCLK and external voltage options but that is mostly dependent on CPU "silicon lottery". As opposite from 7800x3D, 9800x3D has some OC ability. (in theory).
