Photoshop problem on new Imac 2020

How is photoshop working on the imac 2020? Got the 5700xt 16gb, 1tb storage, 64gb ram.

And it run worse than on my 2012 imac! It had some fan problems, so its been returned. But dont know if it was this particual machine, or the entire 5700xt or adobe.
The grapich card has allready had its problem. A grapical glitch, but it got fixed in a software update.
