current setup is:
MB: MSI H510M-A PRO
GPU: Gigabyte intel arc A310 Windforce (x16 physical, x8 4.0 utilized)
M.2: PCIe 3.0 x4
The requirement is to add 10GB-sfp+ card (currently looking into Intel X520-DA1). As I understand current, current mobo doesn't support bifurcation (or at least no such option in current BIOS firmware and no info in manual), so using riser card isn't an option seems to me (or maybe is, would be nice if there's a solution). If not - looking for a mobo replacement for the same platform (i.e. LGA1200) but to support both GPU and new NIC. NIC isn't purchased yet, so any x4 10Gb SFP NIC is also acceptable.
