But, we warned you about this in the other thread.
It has EVERYTHING to do with the drive. The drive is the biggest factor.
Processor is a much smaller factor, there's an argument that gpu is more crucial a component than processor, which for many users, this is probably true.
For me, it wouldn't be. Because I don't use the gpu. I just don't use it. I use my computer for (possibly) relatively mundane tasks, granted, many of them at a time (at times).
If you buy an iMac with a 1 tb HDD that may as well be the iMac for the doghouse.
I had read a post on here from another user, which I would say is some of the best advice I have seen for someone purchasing their new Mac
"Select a high end SSD storage option, whether it be pure SSD or 2 tb fusion at a minimum, and assess your budget after that point."
In other words, to put it in a way that may be blunt, purchasing the correct storage option can be considered more vital in the process than the computer model itself you're purchasing.
