Dual Streaming PC setup Q's

[sfang]

So I want to see if I can make dual PC setup and stream... I'd like to see if my hardware can handle it and a couple of Q's.

PC 1) Gaming rig

Processor: Intel(R) Core(TM) i9-9900K CPU @ 3.60GHz, Intel64 Family 6 Model 158 Stepping 12, CPU Count: 16
Total Physical RAM: 32 GB
Graphics Card: NVIDIA GeForce RTX 3070

PC 2) Second stationary PC

Processor: Intel(R) Core(TM) i5-2500K CPU @ 3.30GHz, Intel64 Family 6 Model 42 Stepping 7, CPU Count: 4
Total Physical RAM: 8 GB
Graphics Card: NVIDIA GeForce GTX 570, 1280 MB

PC 3) Laptop alternative

Processor: AMD Ryzen 5 4600H with Radeon Graphics, AMD64 Family 23 Model 96 Stepping 1, CPU Count: 12
Total Physical RAM: 16 GB
Graphics Card: NVIDIA GeForce GTX 1650 Ti

So questions:
1) Does my secondary hardware have enough to be a streaming rig?
Games that would be streamed are:
Apex Legends, CS2, and some other maybe WoW.
2) What would the performance difference be for my gaming rig to use a secondary streaming rig vs just to have it on the same machine?
3) What video capture card should I get? I've heard elgato would be nice but if so which one?

PC 2 is a bad solution. You will not receive any advantage.

PC3 looks good if you stream via NVENC.

It makes sense to do all this if you want to completely deload your main PC to achieve maximum gaming performance. You won't get any advantage in picture quality.

You can try the free NDI program. The plugin consumes negligible CPU resources. You will need a network cable.

DistroAV - Network Audio/Video in OBS-Studio using NDI® technology

This plugin adds simple audio/video input and output over IP using NDI® technology. Three integrations are currently available: - NDI Source: add NDI Sources into OBS like any traditional source - NDI Output: transmit the main program view over...

A video capture card is a more reliable option, especially if you have a console or digital camera.

You won't get an advantage in quality, because the latest generation NVENC H.264 is roughly equivalent to x264 medium (actually a little worse). So to get higher quality as opposed to NVENC, your processor must encode video at x264 medium and higher.

I should've said that i'm a newbie.
When you say quality do you mean in the streaming quality output? I'm not seeking more than 1080p.
When you say NDI program and network cable do you mean instead of a video capture card?

I think I would like to go with the video capture card if its more reliable... which card would be suited for my needs?

As I stated in my earlier message im not advanced in streaming, i'm a total newbie... so when you say quality what kind of quality are we talking about?
Are you talking about advantage with my gaming rig to stream? I'm pretty sure I'm after the performance and not quality.
Would you also see the laptop as more sufficient as a streaming rig?

In terms of performance what would it be in terms of FPS while in game?

When I say quality, I mean the picture quality that the encoder is capable of providing. NVENC encoder, x264, in your case.

The point is that if you use the NVENC hardware encoder on a GTX 1650 Ti video card for streaming, the picture quality will be the same as when using an RTX 3070 on your main PC.

The NDI program is installed as a plugin for OBS Studio and transmits an image over a local network between two PCs. It's free!

Regarding FPS, this is a rhetorical question.

When it comes to choosing a capture card, it all depends on your budget. In my opinion, Elgato HD60 X is a good option, but there are also cheaper solutions from other brands. I can't say more since this is a Windows support forum. You can ask around on Discord OBS https://discord.gg/obsproject

What would the big negative aspects of doing via NDI program and over the loocal network between two PC's?
Also I use Network cable already in my gaming rig and there is not another port for a network cable on that rig.

The elgato HD60x costs around €270 which is a hefty price indeed...
