What iMac did you get?
The M1 iMacs are pretty nice, but I was thinking maybe the M2 version will be out later this year. Plus I like having 32 gigs of Ram, which you can't with the current iMac.
24" m1 with 16GB of ram 512 Ssd. I had a 2019 27" i9 iMac w/40GB of ram and a Vega gpu. Pretty much top of the line. After about a year, when I would stress the system it would just turn off. At first it was once in a while, then it was once a week and then it became constant. I brought it in to Apple and of course they could not duplicate the problem. They did give me a nice trade in for the old machine and I have been very happy with the iMac. I use light room and photoshop and it feels the same as far as speed. I don't mind the smaller screen at all, sometimes the 27" was too big.
