Bingo. That’s more common. This series focused on reliability over power. They’ll take just about any Pe video card but things like ram fall into very narrow matched compatibility.
More than speed and design there’s height factors and width.
The PCIe sockets have lower clearance than standard ATX as well. And the cross-fire isn’t game level. Running at 4x or 2x speed, it’s intended for GPGPU usage. I it’s high fault tolerance and ecc memory your looking at cryptography or encoding or the like. CAD/CAM, etc. Lots of work with small chunks of data.
I think the most common arrangement is using on CPU video and running two graphics cards as compute cards. I know the board is popular for cryptocurrency and video compression encoding.
