I have only a PCIe 2.0 x4 and a PCIe 3.0 x16 free and I need to install a 10Gbps SFP+ card and a graphic card for transcoding with Jellyfin (the CPU is an old E5-2620 v2). Since I can’t find any SFP+ card that is x4, do you know a graphic card with decent transcoding capabilities (I’d day 2 4K simultaneously) that is only PCIe 2.0 x4?
Edit: the x4 slot is full length.
My Arc A380 has been great. Intel Quick Sync is so well supported across all platforms.
Arc A310 is also a great option since you can find them in single slot low profile varieties too.
