8gb is enough but having 16gb will probably better for the long run, but if your really don't have much money then just go for a 8gb.
if you don't have money now but you will have money later then just buy 1 stick of 8gb 3200mhz ram, then you can just buy another one later when you have more money. Although if you go with this option then I would recommend going for an intel build, as amd systems don't like single sticks of ram.
8 is barely cutting it in 2022, and youre definitely gonna have some noticeable issues here and there

Likely around 16 GB of ram should be enough, but I'd recommend more as it would improve the quality and performance of the recording, and especially streaming.
