Are you gaming on PC or console?
If you are gaming on the PC, you should take a look at the Asus Xonar DG soundcard (or some of the more expensive Xonar models). It has a headphone amp and has some good reviews (I don't own it, so I can't confirm).
I don't have a headset, but I was looking for one. The Sennheiser PC 320 and Steelseries Siberia v2 both get good reviews and are within your budget. But again I don't own any of them.
You also might want to take a look at a headphone and separate microphone (that's what I'm doing right now: http://www.head-fi.org/t/635697/sennheiser-hd-439-good-all-round-headphones). I have been told that for the same budget, you can get better sound quality.
