Hi, I am in possession of the GTX 760 and FX 6350. The equipment actually has its years, and yet shadowplay is great for recording, sometimes even at 2k, unfortunately I am not able to set OBS for streams. My friend has GTX 1050 2 GB, which is weaker and Intel i5 4th generation, my equipment performs better in games, while his in streams. Internet have upload to 10 000 Mbps. I would count on a smooth stream in 720p and 60 fps
