Is it worth it to buy a sound card such as $30 xonar to use. Is it also worth it to get one of those super expensive $100+ headsets. I've got a simple logitech g230 headset that I got in a bundle (2 Channel) that works fine and I'm wondering how much buying an expensive headset improves quality/experience over my regular ol' headset. On another note, since I honestly enjoy messing with my pc more than actually using it, can a sound card be liquid cooled and overclocked?
