Where do you have frame drop issues on your intel Mac? I have a 2017 15 inch with the best i7 and run a 4K and 1440p monitor with no noticeable issues. Just ordered an M1 Air.
Maxed out iMac 2017 here, I can't wait for a new iMac with better performance and zero noise. I love the 5K display and the only comparable display is the Pro Display XDR, which I can't justified.
It does all the time, when I run anything that taxing the CPU. Switching app doesn't feel instant and I can always hear the fan noise going in the background.
