That's not how it works. The only part of the computer that handles any sort of broadcasting tools is the broadcasting capture card and encoder, like from RTS, which can handle high-quality data transfer through an Ethernet cable to the media server. which later you can connect to the main station,SDI, rvon, key panel, etc. All that part is controlled through a different power supply, so if they do have the 4080 like the previous said, then their PSU should be enough since and 9000x3d is known to be efficient. So you don't even need to bother with those external parts since they're mostly compatible with newer computer hardware, hence why each part could cost tens of thousands. Upgrading the CPU itself would help with the data transfer, since it does take away CPU performance, so yes, even if they choose a more expensive 20k parts, it should be pocket change when one of the video encoders itself costs 20k, let alone the whole setup that can go to hundreds of thousands. Also, you can even see from VCT Americas how much cable is coming out from the PC, it's much less than my workstation.
