"I like a lot of features. I especially like the GPO Update (much easier to remotely force a GPO update). In Server 2012 this is an option, but we are on 2008 so this makes it much easier when applying GPO changes."Ian Zahorik

The GPOs reaches the individual computers periodically, say every 90 minutes. If you wish to update the GPOs manually you can execute the GPUpdate utility available in the client computers, which is time consuming. GPO update tool helps in overcoming this challenge.
