Hey guys, I'm looking to improve the sound on my system and my mate swears by a dedicated integrated sound card. Now me personally I have never owned or used one before. The mobo that I have is GIGABYTE GA-Z77X-D3H Intel Z77. I mainly use my pc for gaming such as bf3, swtor, resi 6 etc. I also always use my turtle beach headphones for the gaming and also for movies or netflix etc. Will I notice a difference? Or would it be worth it? I do get a bit of interference using the on board but once audio kicks in I can't hear it. Thanks for the help
