My System Specs

Default

The difference is actually in the controller, not the memory. When it's dual channel the controller can access 2 sticks at once, quad channel it's 4 sticks. I have run 2 sets of dual channel sticks as quad channel in my X79 rig with no issues. The key is to have identical memory sticks in all slots.

As for gaming performance, I'd doubt you'd see much difference as most games are GPU limited, not CPU or memory speed limited. Daily use, you'd probably not notice a difference at all. It's only doing something with tons of computation like folding, rendering, and maybe video transcoding that you'd see an increase in speed.
