Hardware Recomendation for Mosaic 6-8 displays 4k vertical Wall Display

Hi there,

So far we are successfully running different Mosaic setups on Ubuntu Linux with Quattro A5000 cards.
For Setups up to 8 screens we use the NVLink between 2 Cards, for 3 cards we use a Sync card.

What would be the good way to go with the new RTX 4000 ADA cards?
As far as i see all the new cards are missing the NVLink. Does that mean mosaic with 2 cards always requires a Sync card? Or will the mosaic work without and sync spanning over 2 cards?

Thanks for your help!
Johannes
