Building a Blackmagic Machine

[Lukas2]

Budget: Prefer cheaper, but will pay whatever is needed to get the system off the ground.

Country: USA

Aim: This computer will be used to run broadcasted events, including processing NDI inputs and multiple capture cards. We currently have a Blackmagic Quad 2, Blackmagic Quad HDMI, and a Blackmagic Mini Monitor HD that need to fit into the system... and work.

Other details:

While I anticipate using a latest-gen i9 processor, I'm open to AMD. We'll likely have a 3070 or 3080 Ti in place to cover our graphics rendering needs. I'm competent so I don't really have any questions about finding RAM, PSU, etc.

 

The main issue is finding a motherboard that can handle the PCI workload we are throwing at it.

The Quad 2 uses 8 lanes.

The Quad HDMI uses 8 lanes.

The Mini Monitor HD uses 1 lane.

 

We also want to use an M.2 for the boot drive, but that's negotiable.

I've done some research into PCI lanes and how some are CPU, some are chipset, and so on, but honestly I could just use some assistance in recommending a motherboard that will make sure I don't run into problems running all these cards.

 

Thanks so much.

This is the only non hedt board I know of that can do x8 x8 x8, and have a empty x1 https://www.asus.com/Motherboards-Components/Motherboards/Workstation/Pro-WS-X570-ACE/techspec/

 

I'm pretty sure intel doesn't allow a x8 link from the chipset on lga 1700, and I don't know of a board with a pcie switch.

 

The other optioni is hedt like x299, and threadripper, but Id argue those won't be needed, and likely slower for most of these uses as there all a older generation.

I'll also include the Tech Specs on the Blackmagic cards. Since maybe I am not actually in need of that many lanes? Just slots?

Good advice so far though, open to other thoughts.
