4x4k + GUi

[AdamDGK]

I'm looking for a solution that will provide me with a GUI. I need 4x4k with mosaic. I want to add another nvidia card to the system and the question is what is a better solution? render processor and gui gf4080 + quadro a4000 as a monitor that will only synchronize the outputs. Or a4000/a5000 render processor + quadro 4000 only as GUI on resolume menu. Thank you for your help
