New builder, needing some help!

I’ve been a fan of the idea of pc gaming, and always have. Currently, I am wanting to build a pc but I don’t really have any experience with pc builds unfortunately. I bought a pc prebuilt a long time ago but it’s finally died a few weeks ago, so I’m looking to finally build my own.

My price that I’m willing to pay up to is $2,000. My goal for the pc is to play games as powerful as I can, be able to stream them for YouTube, and even record/edit videos. I’m aware that some are saying that you should set up a dual pc for that but frankly I don’t want to set up that much money again for a second pc after this one. Unless it’s absolutely impossible then I’d prefer to do all of my stuff on one pc.

Thanks for reading!
