Getting the Right Rig
Hardware is one of the biggest hurdles most live streamers are going to face. Not everyone is gifted with Daddy's credit card, so running down to Best Buy and buying the most badass PC off the shelf is not always an option.
Luckily, you don't need anything super powerful. You just need to have a basic knowledge of things like bitrates and streaming software (like OBS or Streamlabs for example). That might make your eyes gloss over hearing that, but after a few YouTube videos and Google searches, you'll be on your way.
You'll see a lot of other creators using fun gadgets, like stream decks for example, but at the end of the day, none of that is necessary to create content. A basic mid-level desktop is all you need, or just a next-gen console like PS4 or Xbox One if you want to keep things real basic.
