Configure IE10 - Which Settings by IEAK and which by GPO?

Hi everybody,

I want to re-design our GPOs and IEAK configuration for the IE 10. 

I wonder which settings I need to set by IEAK and which by GPO, because there are some which you can set by both ways (which is not recommended). In a Technet article it says: 

"Because Group Policy Preferences and IEAK 10 use asynchronous processes when they run, we recommend that you choose to use only one of the tools within each group of settings, for example using only IEAK 10 within theSecurity settings or Group Policy Preferences within the Internet Zone settings. In addition, it's important to remember that policy is enforced and can't be changed by the user, while preferences are configured, but can be changed by the user."

Is there a recommended way how to split the settings?
