Any thoughts on how well an RX 9070 XT might work on an X470 motherboard with PCI-e 3 and the CPU above? Will the interface hold it back a lot or, will PCI-e 3 still provide enough bandwidth for it to work reasonably well? At some point in the next year or two, I do intend to move up to AM5 but, can get a reasonable B550 motherboard with PCI-e 4. I don't want to wait that long for a new GPU, because of new developments in The Elder Scrolls series.

I was annoyed at the explicit firmware removal of 4.0 negotation rates as well on x370/x470
Probably not much for the GPU though there's a 4090 PCIE scaling review but it was like 3% @ 1080 and 2% at higher res

Even the dropoff from pcie 2.0 isn't severe so you should be aight

NVIDIA GeForce RTX 4090 PCI-Express Scaling
The new NVIDIA GeForce RTX 4090 is a graphics card powerhouse, but what happens when you run it on a PCI-Express 4.0 x8 bus? In our mini-review we've also tested various PCI-Express 3.0, 2.0 and 1.1 configs to get a feel for how FPS scales with bandwidth.
