I've had the HD700 and they are awesome for gaming but imo the 560's blow them out of the water. The soundstage might not be quite as expansive as the HD700 but the detail and clarity is just much much better. Being able to pin point locations of sounds sources is much easier and better on the 560. I personally use my 560's for gaming, music and movies and regular day to go youtubing. I also add some warmth to the sound sig with my CEntrance M8 by using the impedance switch and bass boost. It adds some decay in the lower end that the 560 desperately lacks. That said the HD700's need some lower end impact as well but maybe not quite to the same extent since they aren't as bright on the upper end as the 560's.
