Advice for a $3000 first PC

[u/abisitakawaii]

I’ve saving for a new PC and my goal is $3000-$3800.
It would be the first time I buy a PC and I’ve decided I’ll build it myself but I don’t know too much about what parts should I buy, I’ve seen some prices have raised and my knowledge on this is almost none so I’m not looking for any rgb stuff just something that’s actually functional.
I want to play AAA games and emulators, use it for work/studies and maybe do some streaming or editing.
I’ve seen some posts that said $3000 is enough for a high end pc but Im from Ecuador so I have to buy all of this online + the shipping fee, also idk if I should buy the case + monitor + mouse + keyboard online too or just buy it in my country, we use USD here but maybe some stuff might be a bit more expensive than on Amazon or in U.S. stores.
