Hello, for Christmas I've decided to get a new headset to replace my old Crappy IHome headphones. I play games like DayZ and Battlefield 4 so surround sound is important to me. I was looking at the Plantronics GameCom 780 and the SteelSeries Siberia V2 with Built in USB sound card and the Siberia V2 without the built in sound card that goes into the audio input. My audio input is an Integrated - High Definition 5.1 Channel Audio. The 780's are 7.1 Dolby surround but I wasn't sure if it would work with the 5.1 Intergraded Audio. Please tell me if it would work and which headset would be better. I would like to plug a headset in to listen to my IPod but that isn't too important. If either of these are bad choices please direct me to some others. My budget is under 100$. The mic doesn't matter too much either but it would be nice to have a better one. The cables should also be at least 6 feet because my PC is pretty far from where I sit. Thanks for the help, I really appreciate it.
