So my headset (old logitech) has semi-broken and was always uncomfortable. Thinking of buying a new one, maybe this http://www.amazon.co_uk/dp/B0079G2Y52/?tag=tec053-21 I assume my mobo only has 5.1 and therefore I wouldn't reap the benefits of the headset being 7.1? Would I also need a dedicated sound card? Is it even worth going for 7.1? Use for gaming, movies, skype, teamspeak etc. Not really music, but movies yes.
