Is the system capable of running gaming at UTLA with high-quality streams for Twitch?
You're unsure about applying Shadow Play. Let me clarify how it works.
I haven't tried shadowplay before, but OBS can also use nvenc for encoding on the GPU. It's not as good as using an i7 processor.
It should work well, provided your connection supports both streaming and gaming simultaneously.
Components are alike in this case...
