These days streaming games is a hot thing, so get yourself a mike too like in a studio. And when you play just hook it up to Twitch.
Try to get a nice web cam too. And throw in every possible accessory that can make your computing experience a nice one. And of course don't forget to include 5k for Windows and 10k ish budget for all software that you really want to use.
