Ark is tough to run as it is, then to stream it...on high settings...with an FX 4300...and a GT 1030? To stream you need enough CPU power to run the game to your standard, ie 60fps at high settings, AND still have CPU power left over to handle the streaming portion of the job.
In your case, maybe at 720p and maybe at low/medium settings and maybe streaming at a lower resolution might make your ARK plans possible. I recommend picking a less demanding game with your setup if you want to get into streaming. Also, look into what program you'll use for streaming, some are more demanding on your CPU than others.
