    Depends on how you define "real world", when using applications that don't use multiple threads/cores (which sadly is a lot of applications), I think it is helpful in those situations. For applications that scale well though (photo/video export, encoding, some games, etc.) I completely agree. When looking at all computer users across the spectrum I think a lot people will benefit from those high turbos especially on single cores when doing basic tasks in those applications. Though hopefully people who are just doing basic word processing/web browsing/etc. aren't buying an i9 iMac just for that :)

    I'd assume it's fine 80% of the time, but for the more intensive tasks switching off is beneficial just to keep the CPU temps down. I mean temps in the high 80's and 90's just aren't good for a machine.

    I'm antsy about buying an iMac because my studio (26 - 28) gets really warm and I'm afraid how the ambient temps will affect it.

    Maybe that's why mine runs so quiet. I built my studio in my basement and it's chilly in the winter if I turn down the vent, but it's downright freezing in the summer if the a/c is running. I have to close up the vents in the summer. My teeth were actually chattering and I was shivering one time last summer not long after I built it and that was while running an Xbox One X and 4K 27" display. That's when I bought magnetic sheet vent covers that I cut to fit because the sliding control wasn't closing it tight enough. It was in the mid-90s that day (~35C) outside. At my old house my studio was over my uncooled garage and it was a higher level of hell sometimes.

    How can you choose to turn off the boost option ?

    It's a third party app you can download for free or upgrade to the pro version.

    would love to see someone gaming with it across a few hours to see what the machine does. Just running a benchmark is useless for temperatures and throttling unless it runs more than just a few minutes, meaning - run it an hour or so

    Yep. Benchmarks (I’m looking at you, Geekbench) tell us almost nothing when the issue of thermal throttling is at play.
