Populating all of your RAM slots with matched RAM improves your overall bandwidth. A 2x8GB set will run in dual-channel mode, the 4x4 set will run in quad-channel mode (if the CPU supports it, most times it's dual-channel.) The 4x4 set will allow for more bandwidth vs the 2x8. Not quite double, but it reaches at it. Every other metric doesn't really see much of an improvement, though, so this only helps out in bandwidth-intensive applications.
