It will be here Monday. Right now I am trying to decide if I want to delid it before installing it.
I am pretty sure that there is a diminishing return higher you go.
Make sure it works first before you delid it. Otherwise you might have a dud that you can't return.
Each equal step up is a smaller increase in performance. Going from 1.0GHz to 1.2GHz is +20%, but 4.8 to 5.0 is only +4.2%. Because you are wanting to compare the same chip that makes CPU performance difference based purely off of clock speed.
