I'd imagine the 5xxx series from Nvidia will be. Of course it won't matter until highend 7xxx series I'd imagine.
While it probably will be on paper, it's just not going to matter for a very long time. If I recall correctly, the 4090 is the first card to fully saturate the bandwidth of PCIe Gen 3 x16, and only just barely. And as a reminder, each generation of PCIe doubles the bandwidth. So where Gen 3 could handle 8 Gt/s, Gen 4 can handle 16 Gt/s, and Gen 5 can handle 32 Gt/s.
Put another way, the 4090 only needs Gen 3 x16, Gen 4 x8, or Gen 5 x4. Future cards will need to double the current bandwidth needs of the 4090 to saturate Gen 4 x16. It will then need to double again from there to saturate Gen 5 x16, having four times the bandwidth needs of the 4090.
I'll be genuinely surprised if we're there in less than a decade from now.

Ya, it wouldn't be a problem for pcie 5x8 until highend 7xxx series(IMO) I'd say. Not that it matters for my situation. Considering I dun goofed and got confused by the boards. 
Not that it matters. I'll just use one pcie5 ssd and use the whole 16 lanes on pcie 5. Even 2030 shouldn't be a problem with that, unless gpu architecture goes crazy.
