And look into these audio interfaces, especially USED:

PreSonus or Scarlett or Behringer. Those can be had starting at $50. And used ones will work just as well, check on Ebay. Then pair it with an XLR condenser mic, which you can get as low as $20. There are a lot of condenser mic clones from China on Amazon and Newegg that come with the whole kit: mount, pop filter and arm. The brands above also sell whole kits, but seem a bit expensive. You can always upgrade piece by piece later if your channel gets larger. The USB audio interface will work with many mics.

You should try searching for other posts in this sub that ask the same questions. I'll just paste my answer from another post:

You can go cheaper on the mic itself, if you pair it with a decent USB audio interface, like PreSonus or Scarlett or Behringer. Those can be had starting at $50. And used ones will work just as well, check Ebay. Then pair it with an XLR condenser mic, which you can get as low as $20. There are a lot of condenser mic clones from China on Amazon and Newegg that come with the whole kit: mount, pop filter and arm. You can always upgrade piece by piece later if your channel gets larger.

Then use OBS Studio and the built-in audio filters to cancel out noise and gain to boost it. And you'll be able to upgrade pieces as your needs increase. I recently got a better mic arm for my setup, but keep using the same mic and USB interface.
I think a lot of people get frustrated with the pure USB mics, which are either too sensitive to noise, pick up the electrical interference from the PC, or don't have enough gain.

Also, check out YouTube channels that talk about streaming or recording games. They review a lot of equipment and help you with good setups.

Lastly, you will want to use your capture card to get video from your PS4 and capture it with OB on your PC. At the same time, you will capture your mic audio in OBS, to output a video file that will have both the video and audio together. The YT links above talk about how to mix different sources in OBS.
