I plan on using my main pc as an upgrade to my current server.  I currently have Z390i Motherboard, and I want to be able use my RTX 4000 and also HBA Card to connect to my disk shelf.  Curious if this could work without any problems or penalty in performance.  The main role of the RTX 4000 is for my plex server in Hardware Acceleration.

Bifurcation itself shouldn't cause a performance penalty, but sometimes the risers used to physically split the slots can bring a small penalty, or instability if it is of poor quality.

Same sort of issues as seen when simply vertically mounting GPUs though risers etc.

 

It should be noted bifurcation support is via bios and it is invisible to the OS other than the change to vfio grouping
