Finally got my hands on an Intel 10G NIC with PCIe gen3 support.
This series of NIC uses the i40e driver.
I did have to apply a small patch to disable the more niche features of the card that were hogging MSI-X vectors, stuff like VMDq and iWARP.
After the patch, the card works great, no bus errors, and it performs close to theoretical maximum in iperf3

I simply disable the unwanted features before the MSI-X vectors are distributed.
There may be a way to do this without a patch, but I haven't found one yet.
Gen3 PCIe @ x1 has a max speed of 8 Gbps
Next on the agenda is obtaining a PCIe gen3 switch and a Broadcom 94xx raid controller. I tested a 93xx card but it didn't work, upon further researching, Broadcom says that only the 94xx and newer support ARM

I had to double check I didn’t just discover Jeff Gerling on Imgur lol

My PI5 can do composite :P

Nice. That's a level of geekery I can truly appreciate. What kind of storage are you using?

For the pi? I have a "Samsung Pro Endurance" sdcard. For general storage I have a 5 drive raidz on an x86 server that serves as my NAS. The hope is that I can get both a 10G NIC /and/ a raid controller working on the pi5, since that setup would use a fraction of the power and just be fun to build. So far gen3 PCIe switches are hard to come by, but I have a few options I'm exploring
