I'm considering a 2K budget for building a PC itself before any peripherals, but it would most likely increase to ~2.5K. My laptop lacks enough oomph to output streams from OBS at acceptable quality and decent bitrate, and noise gates set on my mic can only do so much (will use VST plugins from Reaper). Even the simplest games are enough to push the fans above my mic's noise threshold. It's an unavoidable problem due to needing to check audio and video sync, and because it's the only location at the moment I can mount my webcam to. I'd focus first on a 1080p 144hz freesync monitor with minimized input lag that's perfect for most of my games. Eliminating input lag would be a major boon compared to gaming on a television. At some point I'd get a 4K monitor with HDR so I'd be able to stream PSVR and PS4 Pro enhanced games to their fullest extent. It would be a challenge for PSVR streaming, though. I'd have no intention of subjecting any viewers to the fishbowl view, but that means my only way of interacting with chat and monitoring it would require implementing a text-to-speech plugin in OBS that reads input from chat. Quite the hassle, but it would be worth the effort in the end... Budget honestly isn't a major concern but I'm clearly not going to buy everything at once either. It's better taking due diligence to build a good design that's easy to upgrade at my leisure.
