Two Firepro v7900 for Multi Monitor

I have run multiple monitors for years for my business; 6-8 monitors on a systems. Always Nvidea. Currently using four cards running out of hdmi port and dvi port with hdmi adapter.  I am looking at switching to two firepro v79000's with hdmi adapter; ASUS x370 MB. Will I have any problems? My systems are pretty much plug and play with no tweaks needed.
