I consider to buy the base version of the Mac Studio to replace my Mac Pro 5,1. I am however disappointed by the Geekbench GPU score (Metal) 51000 (Max 32c) and 103000 (Ultra 64c) (vs 194000 for an iMac with the best videocard!!!). Also now I have only my computer on my desk, with 6 drives in it. This was handy, I could easily open my MacPro and upgrade. Now there will be several boxes on my desk. I have used the MacPro for 12 years, I think I will use the MacStudio only for six years, so therefore I won't spend extra money for the Ultra. It would be too expensive. I also deeply regret that Apple won't sell the iMac 27 inch anymore.
