beats by dre are not very good headphones. they cost at least double if not triple what they are worth.
with that said, as far as headsets go the astro is pretty well respected though overpriced.
if you already have a soundcard capable of virtual surround (or if you dont care about virtual surround) i would personally use a good pair of studio headphones. if you want better soundstage than perhaps the dt880, dt990 or hd598. if you want very bassy but smaller soundstage perhaps the m50 or dt770. for a mic you could use a modmic.
if you absolutely must have an all in one... perhaps the pc363d (its light on bass but has good sound quality)
