Since your looking to buy new headphones, mic and sound card. The headphones and mic combined staying under $200. maybe you could think about this: ASUS XONAR. Considering the headset you get, which to my understanding is exceptional, and you get a high end sound card, which is a lot cheaper than buy everything separately. The headphones have been modified to bring out the full potential of the sound card (or vice versa). They even use those massive professional level audio jacks.
