If I added in any superfluous information, it may send the thread into an argument; a direction that would be unhelpful to everyone. So I decided to give only bare bones information and let your guys' imagination go to town. And so far, I've seen four very interesting builds.
One thing I have to mention though, is everyone is mentioning a Titan RTX, a card that is easily taking up a third of the budget. I'm afraid I have to say that I will not be buying a TITAN card at all because I have no plans for its compute abilities. It's a gaming/video rendering station after all, not a deep learning supercomputer. If it doesn't provide a significant boost to OBS video processing performance (EG: 4K/8k recording while playing at 4k/8k resolutions without lowering quality settings or dropping frames), I can't see myself justifying it's purchase - even with it's machine learning prowess.
