Streaming my sim sessions to YouTube - hardware setup?

I want to stream my sim sessions for fun and maybe grow a small YouTube channel. Currently have:

• RTX 3070 GPU
• Ryzen 5 5600X
• 32GB RAM
• 1080p projector

Questions:

1. Can I stream and run GSPro on the same PC or do I need a separate streaming PC?
2. What capture card if I need one?
3. Best camera angle for golf sim content?
4. Any streamers here willing to share their setup?

Not trying to go viral, just want to share rounds with friends and maybe make some content.
