Hello guys , we have an opportunity to create a PC and I'm not sure what would be the best option . For now we are using 2 BMD Duo 2 , but looking to upgrade to 4k in near future at least a part of the prod . due the lack of pci lanes (for 12th gen) as 8k pro require 8x

From Vmix reference systems on 4k + replay "Diamond" , it is recomended i9 10980XE (hard to find , also on many distribuitors x299 MOBO it is out of stock for a long time )

Did anybody already using the use 12th Gen CPUs with vMix? Any issues to look out for performance and stability ? Is still a good option the 10th Gen ? Due the need of pci lanes but it gets preatty old , I'm affraid just that Intel will move quickly and 10th gen will be obsoleted , now is hard to find some components for X-series I don't want to imagine what will be in one year.
