New PC Time

All,
I am looking at putting together a new PC.
Ryzen 5950X
Nvidia 3080
Memory/Case/PSU/Cooler is easy after that spec

I will need a PCie 4 X16 slot for the graphics card

I plan on installing an Asus Hyper M.2 X16 Card V2 that wants a PCIe 3 x16 (or x8) slot for more onboard high speed storage

I will also need a slot (PCIe 2 X8) for the 10Gb fibre card although I could use a 10Gb copper port on the motherboard, if it has one

When I start looking at motherboard specs they confidently headline that they have 2 (or 3) * x16 slots, but when you look deeper they all seem to caveat that with 1 @ X16, or 2 @ X8, or even 3 @ X8 which isn't ideal

If I stick a 3080 in a PCIE 4 X16 (running at X8) slot what sort of performance hit am I going to see?

Ideally I would have 2 slots running at X16 plus PCIe 2*8 slot for the network card - but I can't find one.

Am I missing something, being stupid or what?
