Well I have no sound card because face it Onboard has come a long way. Plus I'm useing a reciever instead of some cheap computer setup. In my time I have bought the Logitech X-530s for listening to my music and it wasn't working for me. Like my friends say I abuse my setups. I would play my X-530s as loud as possible and it wasn't loud enough. I like to jam and I love to piss my neighbors off with my music. I even had the Klipsh Promedia Ultra and that was loud enough and had good quality for a little while. Two months rolled by and boom a speaker blew. So my advice to all of you if you want good sound quality and you want to piss your neighbors off. Go with a reciever and your own speakers and such. I'm a big computer gamer as well and I haven't used my Headphones in probabbly 3 weeks since I got this. I still here every little thing (footsteps and pinned grenades). Now I can easly tell which direction the sound came from due to the 5.1 instead of just 2 headphones.
