Hi Darryl. I’m sorry for the long delay. I really appreciate your help. I was with a health problem. I'm OK now.
Based on your advice, this is what I’m thinking to buy:

27” iMac with Retina 5K display
3.7 GHHz 6 core 9th generation Intel Core i5
32 GB 2666 MHz DDR4 memory
Radeon Pro 580X with 8GB of GDDR5 memory
1TB SSD storage

Pro Tools update to:
2019.6 OS 10.14.6 Mojave or
2019.10 OS 10.15 Catalina (maybe too recent)

Any comments? Thanks again.
