Question: what pc do streamers use?
Answer: The Gaming setup could get away with an i5-6600k, 16gb of RAM, and a GTX 1070. But the Stream box would need something like a Ryzen 7 1700X, 32gb of fast RAM (2800 speed or higher) and a cheap GPU (GT 1030 is perfect.) You would also need a Capture Card, so something like an Elgato HD 60 Pro, or a Magewell card.
