I have an iMac Pro with 64 RAM and it is still in the return window. I'm wondering if I should consider ditching it for a i9 8 core 2019 iMac with similar specs and save about $1400 (by adding my own RAM from OWC). I have not seen any conclusive breakdowns saying if the new iMac i9 is having any excessive fan noise like the 2017 models when under stress, although I have seen some posts saying that people were hearing more fan noise at idle. I've seen videos showing that there is no throttling, but they can run hot. I use the iMac mainly for audio production so noise is a consideration but, for a difference of $1400, maybe I can tolerate a little noise once in a while? ASLO, sometimes when I record vocals, I have to turn off the AC and the ambient air temp can go up, causing the fans to come on... especially in the summer. Are the iMac pro's cooling system and T2 chip, etc really worth the price difference? Thanks!
