I'm looking to build a vmix PC with about 30 input sdi with w790 mainboard, Intel Xeon W3400/2400 and GPU Quadro A5000. I don't know if vmix has support to optimize for that hardware? Or can someone suggest me how to build a PC vmix around 24-30 inputs (x3-4 Decklink Quad) .png "W790 WS")

You won't like this answer (and as a vMix enthusiast I hate to say it) but that many hardware inputs isn't well suited for vMix. And it's not vMix's fault either- general purpose PC hardware just doesn't fit this use case well. I run a 16 input machine with an A6000 and it chokes sometimes. (This is due largely to my build being a dual socket so NUMA / the CPU interconnect fabric is being largely tapped out.) Every few years Netflix releases slides about how they improve their architecture to work better on multi CPU machines. It's worth a glance: https://papers.freebsd.o...eebsd-400gbps-slides.pdfIf you were to try and do it, you've picked the right CPU (super high PCIe lane count).
