System starting from GPU: Radeon RX 7800 XT and CPU: RYZEN 9900X

[Petet]

I decided to switch from an old INTEL to AMD, but I don't know anything about AMD

GPU I already bought it. Sapphire AMD Radeon RX 7800 XT NITRO+ 16GB Graphics Card
CPU i want Ryzen 9900x

please recommend the other components

NO budget limit, I'm not interested in how it looks, only the utility
I want to use the system for video editing, I can't wait until the new AMD motherboards are released ....

Thank you

You've switched so do you already have anything else? PSU? Case?

i have but the case is mATX and is too small for GPU
and PSU is good, is modular Seasonic 750w, gold, but i dont have PCI e cable from psu to gpu and i dont know witch one to buy

If

If your doing video editing, is audio quality also important to you?

not so important, why?
