–> this might suggest that you get a standard 1TB fusion drive (for on-board speed + moderate storage) and then add an external hard drive as needed for archival + backup + additional (slower) storage max out the size + speed of the hard drive.–> this will be an option after you pick the iMac or iMac Pro –> this will be one choice to help you select between different models of iMac or iMac Pro –> this translates to a requirement for an i7 processor rather than an i5 processor more cores are required to run multiple copies of apps and for the (occasional) need to run Windows in a Virtual machine.The graphics hardware must be as fast as possible. –> The computer must be able to run full bore on all possible cores with all possible threads. This translates generally to more cores + more RAM + larger hard drive. –> The computer must also run Windows in addition to macOS.
