It's not a fancy Elgato but this is the capture card I use for streaming and recording stuff from console. It works just fine in my opinion - highly recommend if an Elgato is out of your price range or if you're just starting out! Would recommend pairing this with a HDMI splitter as if you play your game through OBS, you,ll get slight delay. A splitter resolves that.

The mouse I use. I don't have anything special to say about it. I felt like my aim improved with it when I upgraded to this over a budget gaming mouse.

This is the headset I use. It works pretty well for me trying to hear things in competitive games

This is the microphone I use for streaming, recording and just playing with my friends. It sounds really good especially for the price!
