Use the auto-config within OBS Studio.
No one can tell you what optimal settings are as it depends on the EXACT workload, and hardware resource utilization on your computer. Operating System settings/optimizations come into play, as well as all background processes/tasks, etc.

An i3 is low-end, but relatively modern CPU. 8GB RAM is on the low side... so with careful (not excessive) expectations, you should be ok for some real-time encoding. I'm guessing low-end laptop, so no discrete GPU? So you'll probably want to make sure you are using Intel QuickSync video encoding. Stick to 30fps (or similar)

Dwayne - one thing to be aware of is real-time video encoding is computationally intensive. Meaning things inside that might get warm/hot. I recommend learning the specifics of how to monitor for thermal throttling with your specific make/model laptop.
For short OBS Studio sessions, probably not an issue, if you hadn't done something ahead of time to get machine hot.
But we often gets questions about why machine starts out fine then has problems after X number of minutes on a laptop. Thermal Throttling (ie CPU, NVMe SSD, GPU, etc slowing down to avoid overheating) can be a real issue and there isn't a standard way to monitor for it. So you'll have to do a little research to figure out how to do such monitoring for your specific machine

So it sounds like we might need to build a desktop computer specifically for this.

uh... it depends. I ran 1.5hr long 1080p livestreams on a workstation laptop for quite some time.

There are folks on this forum who are masters of both Operating System and OBS Studio optimizations, and can get 1080p30 streaming working on fairly under-powered, old hardware. BUT... depending on what you want/expect, and desired settings. It is also not hard to bring a US$5K workstation to its knees depending on settings and what you are trying to do. it really does depend on a LOT of factors... All real-time video encoding system make assumptions with default settings that aim to balance end-result video quality and hardware resources to produce that. Whether you are ok with those assumptions, need to adjust, etc... is up to you to figure out

If you don't want to limit yourself, and focus on presentation/appearance of stream... vs time on OS and OBS configurations, then over-powering your setup may be in order, presuming you have budget for it. Then there is how long you want a system to last? Buying something that can handle 1 or 2 video inputs and simple 1080p30 H.264 stream without a lot of spare capacity, could easily choke on future upgrade to multi 4K camera inputs, and AV1 encoding likely standard in a few years. A desktop PC will be more flexible, with easily upgradeable GPU, etc, which I'd rate as more important if you want a longer life out of this system

It is really for a Church live stream set. I recently purchased a Avkans PTZ camera to upgrade the video quality. Also we only stream to facebook live, but want to now explore YouTube as well. Another issue is I am in the rural area of Jamaica and the internet is not so great. (download speed is about 40-50mbs and upload at about 20-25mbs). I am wondering if that is adequate for a decent enough stream to both platforms.

I am wondering if that is adequate for a decent enough stream to both platforms.

From OBS Studio, simultaneously streaming (ex Facebook and YouTube) requires approx 2X the upstream bandwidth. 20mb/s upload would be enough for both streams, but you need to be aware of ALL other traffic using that WAN link (guest WiFi, office computers, etc). Regardless, setting up Quality-of-Service network settings so stream traffic gets priority would be a good idea.
An option would be something like reastream.io where you send a single stream, and an external system/provider then repeats those streams to various providers (changing/(re-)encoding video as required)

However, for House of Worship (How), I'd suggest you consider the following
- will having comments in 2 places be conducive to community?
- is the issue that some folks don't want to use Facebook (for good reason)?
My approach was to use Facebook's Scheduled Video feature, which means EVERY service is at the same URL, .. and.. you don't have to log into FB to watch (for the security conscientious, I do recommend using Incognito mode of a browser for when connecting to FB URL). For those who want to watch the service on their TVs, they can add that static URL to smart TVs, Roku, etc ... no need for YouTube

I'm of the 'keep-it-simple, ..' approach... hard enough getting trained volunteers to run livestream setup in first place... why complicate it with streaming to 2 places at once. Now you need a Digital Usher for both... and what do you do if 1 crashes during a service but the other is working fine...etc. There could be good reason to use both, but personally I'd consider dual-platform streaming as a last resort for HoW, where community is at least as important

I had numerous requests initially for adding YouTube, but I was able to explain why it wasn't necessary and got leadership support for having a single place to watch services
