The HD580's are the best i've found for the price, (i've got my pair right in front of me now)
but for gaming, i think they are a bit of an overkill. Gaming isn't that great on sound quailty and its more bass stuff, well in my opinion anyways. The HD580 and others in that range are more for proper music listening and have superior sound quality (hence the price, though i still think they're a tad to much).
you'd find something just as good (as far as you'd be able to audibly hear), and with alot better bass for alot cheaper, if they are only going to be used for gaming , look into Sony.
though still, the HD580 are the best audio purchase i've made if you're looking at them, i can recommend
cheers
