Hi all. I am looking to build a liquid cooled Vmix machine for recording/streaming. I was wondering your thoughts of the following system components:

AMD R9 5950X
RTX 3090 (or newer being released May)
Gigabyte X570 Aorus
32 GB DDR4
2TB Samsung SSD

I am looking to accomplish a production which will include a host (local), a Co-host (South America) and 1-2 guests (mostly USA based). I realize that internet speeds will play a big part in the success with 2-3 Vmix Calls.

The production (at times) will be live streamed but will mostly will be recorded and then put together in post production. I would like to record isolated audio/video for all parties involved. I am wondering what is the most efficient way to do this. Will this PC (mentioned above) be enough?

I did see a tutorial online in which a couple Apple TV’s and an Atem ISO to record the isolated channels (people in my case). In the video NDI was used to get the signals from Vmix to the Apple TV’s. Is NDI the only way? Is it the best way?

I appreciate all the help and thank you all ahead of time for your assistance.
