So I was wondering if it would be better to have a render farm or just buy a really fast computer.
A render farm of really fast computers…
But if I don’t have enough money for that then which one?
Do the math. How long does the really fast computer take to render a single frame? How long does the slow computer take? Figure out how many slow computers would be needed to match the fast one for simultaneous frame rendering. If you can afford that number or more slow computers, then go for the render farm.
You should have one fast computer as your main workstation though. That way you don’t lag just positioning the scene.
