tl;dr: It's underwhelming. A similarly-priced PC (expectedly) outperforms it, and more surprisingly, several professional Mac tools don't take advantage of the extra hardware making them run around the same speed they do on cheaper Macs. Also the display is largely unfit for the use-cases those $43k displays it was compared against are designed for, though it's also much cheaper so it lives in an awkward middle-ground.
