Recommendations for building a dedicated streaming machine

Hi Everyone,

I want to build a machine for live streaming some development projects on weekends. I am going to have a pretty simple setup. I was wondering if I could get some pointers on my set up, see if it seems sane for what I am trying to do.
I want to output a 2K stream to Twitch and YouTube. I really don't want to stress my main machine adding to any CPU usage etc. I'm assuming that encoding would introduce ~ 20-30% constant CPU usage, which would probably be enough to annoy me in some parts. To avoid this, I will probably build a new machine.

What kind of specs would I need to be able to create a live stream? I am thinking that I will make a few graphics to switch between different scenes with Advanced Scene Switcher, so they will play out when switching scenes via some shortcuts. I want to record the video from the Cam Link Pro and 4k60 pro, so they can be edited with Resolve after the live stream.

According to Nvidia, the GTX 1650 GDDR6 only supports 1 NVENC at the same time. What is the hardware that I should be using to achieve this outcome?

The GTX-1650 supports (3) NVENC sessions. The key to getting the correct 1650 with the 7th Gen Turing encoder is to make sure it has either the TU106 or TU116 chipset. The older models with the TU117 chipset have the 6th Gen Pascal encoder.

You're also going to NEED a motherboard and main processor in the system that has more than 16 pci-e lanes, as not doing so will introduce a potentially major bottleneck getting the video feed from the capture devices into OBS' scene composition on the video card.
