ASRock X870E Nova and Taichi are the more affordable boards with lane splitting for the main Gen 5 x16 slot.
Then you have $800 boards like Aorus Extreme AI Tops.
If you believe ASRock's latest BIOS fixed the CPU killing issues, get the Nova.
A good system overclocker with a 9800X3D and Nova used to visit /pcbg/ fairly regularly, I believe his CPU hasn't croaked.

Maybe it was a silicon lottery thing.
