Even the best chromebook in the market (as of 2022) is not meant for recording in high quality. It is used for productivity and/or very light gaming(on the web). You dont buy a chromebook to record anything, let alone stream. The only time i can think of for recording on a chromebook is when you want to use to to capture another device using a capture card. Even then, for that price youcould just get yourself a windows 10 laptop and it would do so much better with recording and streaming than a chromebook. If you really want to stream, then just buy a new pc around the same price. If you really want to stream on ur chromebook, then use apps from the chrome web store, or use the built in linux to download the linux version of obs(though i suggest you dont try this). Note that chromebooks are weaker than a 2008 desktop.
I hate to contradict...
I have an Intel Pentium Silver N5030 in my Chromebook.
You said specifically that a desktop from 2008 would be faster.
So, I researched a significant CPU from 2008 and stuck with the intel core 2 duo E4700
Geekbench seems to contradict your argument.
Now this wouldn't be significant if it weren't for the fact that this is an Intel Pentium Silver, a budget low powered CPU for laptops.
Let alone the core i7 Chromebooks you can buy from the likes of Acer:

But it gets worse.
You said that a PC would have "more cores and stronger ones". Now If you were talking about a DESKTOP PC, I wouldn't argue. But you just said blanket PC. You do know that Chromebooks use the same CPU's as PC laptops? Also, claiming Chromebooks are only for students is also a lie, I actually know an organisation that use exclusively Macbooks and Chromebooks. No windows PC's in sight.
So not only was you comment on Chromebooks being "slower" than PC's miscommunicated at best, misinformed at worse, but your claim that only students use Chromebooks is also, a lie.
Please do your research before throwing claims like that.
I appreciate that it's hard getting OBS to work within crostini, but claiming "they're not up to the task" is just plain wrong.
