PC Spec recommendation for 1080p capture, recording and streaming

Hi all,

I'm helping out a community space and we are hosting a few talks which we are recording and transmitting over youtube using obs studio. Right now we are using someone's notebook, but we'd really like to not need to depend on that. We are in a third world country and money is short though, so we are looking to buy used and seeking help to understand what kind of specs we will need.

We are taking video from two to three cameras (one via wifi, others usb), receiving sound via a p2 cable from a simple sound desk, and connecting a few headphones and a speaker trough bluetooth.

What I am wondering is what's the minimum cpu and integrated graphics or gpu, as well as memory, we'd need to be able to run this reasonably well, possibly with say a few tabs open alongside in a browser, maybe spotify or something like that, but nothing much fancier than that. We'd be capturing and transmitting at 1080p, a I guess a decent bitrate, and not doing anything too fancy with post processing either.

For arguments sake let's say we'd be running windows 10 : p

I've found a few used kits with say 8th gen i5s - would those do? How low can we comfortably go while still using an integrated gpu? Would maybe going for a cheaper mobo and processor combo but a dedicated gpu be better? Would having 16 vs 8gb of ram be a noticeable difference?

I hope this is the right place to ask this. Thanks in advance : )
 
Intel 8th Gen is still viable with OBS but it may or may not be soon. 7th gen & older are already EOL, OBS 27 or 28. Worst case, stop updating OBS when it is phased out.

If you can find a rig with an Nvidia GTX GPU that would be a plus. If you're stuck with only the iGPU as an option, you'll want 32GB of RAM for 1080p/60. If you can only get 16GB, 1080p/30. 8GB is a non-starter with no dedicated GPU & I would argue even with a GPU so don't go there.
 
i5, these look OK & should get you by: 8400, 8500, 8600, 8600k (preferable). iGPU performance scales with the CPU so I would avoid the low power T variants.
 
Thanks for the pointers : )

Supposing we go for a dedicated GPU, what kind of GTX would be good enough to help, and how much would that drop the cpu and memory requirement?

I'm trying to assess whether it would make sense to go for that as opposed to an integrated solution with the possibility of later getting a dedicated gpu for a better "final" system.

Again, thanks for the help
 
My older rig is a 6700k/1660 Super. It still kills 1080p/60. A bit thin on VRAM @ 6GB but will preforn nicely with 8th gen too. Anyway something in that range in the 2000 or 3000 series will work too but your starting to get a CPU bottleneck cause the GPU's are too powerful.
