What am I looking for in a digital audio mobo?

[Reverend]

I'm drooling on BuildmyPC.com and I've chosen the chip.

Intel? Core? I9-14900KF New Gaming Desktop Processor 24 Cores (8 P-cores + 16 E-cores) - Unlocked
Brand:Intel
Model:Core i9-14900KF
Speed:6 GHz
Cores:24
Socket Type:LGA 1700

Supporting mobos have quite a lot of difference in the prices so what are the key specs for digital audio?

Thanks - rev
