As someone said earlier and correctly, you will not see any difference with a non-K I7 7700 with any board you use because the 7700 isn't unlocked like a 7700K would be therefore a Z series board is pointless for you. I mean with TurboBoost the I7 7700 is still going to be over 4.0 GHZ when you are gaming which is plenty. If it were me I would stick with what you have and if you want to improve your gaming experience (if you're a gamer) or even audio experience you can always add a sound card and use a better headset. Other things to consider improving gaming, or just the overall computing experience would be better keyboards, mice, better displays, and of course on the gamer side of things a better GPU.
