Sonoma Installed on 2015 27" Intel i5 iMac is super slow

Sonoma seems to be running fine, but everything is slow, mouse movement is choppy, opening windows slow freezes for 5 seconds, etc. I installed everything correctly, each step taken.

Is it possibly AMD Radeon Graphics card compatibility or issue? Processor not able to handle the OS? Or maybe this hard drive is shot?
