Hi, My question is three-fold... I am debating on whether to buy the iMac i5 9th gen or the i9. I am a using it for Photoshop, InDesign, Illustrator, and eventually After Effects. I know that the i5 can handle my needs, but wondering if I need to be doing things like 4k video editing and such to warrant the i9 making a difference. In other words, will the increase in the advertised speediness of the i9 be noticeable for my purposes? (using an SSD, and will have at least 32gb RAM, so take that out of the equation.) Also, I was talking to Apple yesterday and they were saying that it's not just the speed, but the efficiency/other ways the i9 chip works, which makes it better and have more longevity. True? Lastly, they were saying that heat is the enemy of computers and their components. I have read that the i9 gets hot (they had no comment on that), but wondering if that is only when being pushed to its limit, or if it's just a hot chip in general. Thanks in advance for any insight!
