Looking to upgrade, compatibility question (anarchist.nexus)

Hi! As the title says, I am thinking about upgrading my system for the last time to max out the current build.

Mainboard: Asrock AB350 Pro4 with a PCIE4.0 16x slot
CPU: AMD Ryzen 9 5950X
Ram: 64BG DDR4-3200 Current GPU: Nvidia 3070Ti 8GB
PSU: 800W, more than enough.
Storage: 1 TB M.2, 2TB M.2 SSD /w extra controller in a PCIE 4x slot, a fuckton of HDD storage

I am thinking about switching out the 3070TI with it's measly 8GB VRAM that is simply not doing it for 1440p Gaming with a AMD RX 9060XT 16GB, which is pretty cheap and available right now, esp when i take the resale value of my 3070TI into account, which would account for a bit over 100€ for the upgrade, which is quite substantial in performance.

I cannot for my life find any compatibility information between my Mainboard and the AMD Card. I know i lose a little bit of performance because it's a PCIE5 Card in a PCIE4 Slot, which to my knowledge shouldn't be too much of an issue, but i wanted to ask if anyone has knowledge if there are issues with compatibility here.

PCIe N cards normally work fine in PCIe N-1 slots, so long as there isn't some other problem (like insufficient power). If they didn't, there would be many fewer GPU upgrades in the world. :)

I think you've done well in choosing to replace Nvidia with AMD, since this will lead to a smoother experience (or at least more options) if you ever decide to escape Windows.

Oh i am already running Nobara as a daily driver for a year now, which works fine with Nvidia cards (i expected more issues, but was pleasantly surprised at my smooth experience stability- and bugwise). But the 8 GB VRAM of the card is pretty reliably the bottleneck now - i can monitor usage while playing, and VRAM usage forces me to reduce quality in a lot of games, or live with degraded performance.
