I'd buy a 32 inch iMac as I'd put it to use to make money.
I've used systems with over 1 TB of RAM. It's amazing how fast you can use up resources these days.
I bet it is. But that’s not good enough. You need more. 1TB ram is small fry to you now that you have used it. Must have 2TB. And don’t be silly. You’re moving into the iMac now? 32” is way too small, this is macrumors, we are people, we demand at LEAST a 100 FOOT iMac. Then when you get it, too small, definitely wouldn’t recommend anything less than 200 foot and up.
