One of the things that I like about some (upper?) mid-range boards is the fact that you get so many extra utilities to tinker with. In looking over the suite that comes with the P67A-UD4 and the Smart6 suite, I have to say that when you setup the UD4 you have some very nice options.
One of my favourites is the Smart Recorder along with the Smart Lock. These two can be very beneficial to a parent setting up a system for their kid (or for the paranoid trying to find out who is using their system).
The Smart Recover can be useful for backing up your system in the event of a disaster. However, be sure you are not just backing up to the same drive, as that is pretty much a useless back up.
Another piece of software that is often overlooked is the Dynamic Energy Saver 2. This can control the power to all parts of your system. It has multiple profiles that can be set depending on your usage model and can even let you turn GIGABYTE's new Dual Power feature on or off.
