Using Arc A380 in secondary PCIe slot with 3.0 x1 connection - LastDudeAlive - 2023-10-07

I'm looking at upgrading my CPU/Motherboard/RAM/GPU in my current gaming PC, and so I'll have a Ryzen 5 5600, MSI Pro B550M-VC, 32GB of RAM, and an RX 6650XT left over. I would like to buy a cheap case and PSU, and create a home server to get more experience with a home-lab setup, as I am working in IT. I would also like to have it run Jellyfin (not sure how yet, possibly in a container or VM), as I have a large collection of DVDs, Blue-rays, and CDs I am working on digitizing. I have already started to take them and put them on a 4TB WD Red drive.

I understand that the preferred card for transcoding a Jellyfin stream is an Arc A380, due to it's low cost and excellent transcoding capabilities, and that AMD cards are the worst. However, I would like to keep my RX 6650 XT if possible, for Linux gaming and experimenting with AI. The B550 motherboard has 4 PCIe x16 slots. The top one runs PCIe 4.0 x16 (which would house the AMD GPU), and the others run PCIe 3.0 x1. If an Arc A380 was installed in one of the slots with a PCIe 3.0 x1 connection, would that impact the performance of transcoding? If so, would the RX 6650XT function fine for a maximum of 1-2 transcodes, at most transcoding a 4k blue-ray movie to 1080p?
