for Motherboard Future Prof my 3 PCI cards and Scope Platform I intend to back up my Studio pc by keeping extra hardware, I'm now in a setup compiled with the flowing :
Asus TUF h310-plus gaming
i7 8700k
16 gig DDR4 ram
And NvMe SSD drive.
AND 3 PCI cards: "Luna + Pulsar 2 + Scope/SP"
It seems that i have 99% success with my 3 PCI cards ( Luna + Pulsar 2 + Scope/SP ) with this Motherboard, so for the backing my setup i have two options,
1 - Keep extra motherboard ( Asus TUF h310-plus gaming )
2 - Or to start compelling new hardware for different setup, with this HW in mind: MSI Z97 GAMING 3 + i7-4770K
I can't figure out the best of the two options, I'm trying to set up the most robust PC for 3 PCI cards! ?
All Insight and knowledge is welcome with an open mind

Most things on my mind are Native PCI, PCI overflow, PCI Latency timing bios settings, etc...
Thanks.....

Best,
