Streaming on Twitch - how expensive is the setup?

Streaming on Twitch - how expensive is the setup?

I also streamed over Twich. But that doesn't cost anything, or what do you mean setup?

It depends on how good it should be.

If you have a PC that now runs the games smoothly with good graphics settings and a fast Wi-Fi line, it costs nothing and if you have nothing you can expect 1000-1500 euro

It depends on what you want to stream
