RTX 2080 Super not high-end now? I think you mean enthusiast (Ti/Titan). Unless I'm missing the sarcasm :P
Here what I made on PC part picker with a budget of $2000. Granted you can shuffle things around like cheaper PSU and case and HDD depending on what you need and spend the difference in a higher end CPU for a fairly small gain for gaming. But all are high end components.
