Can someone please direct me as i'm having a little problem understanding this Siberia V2, the version i have is WHITE which means no USB 7.1 card, my question to you now is what is my Siberia V2? Second question, should i get Auzen X-Fi Forte 7.1 or Auzen X-Fi Prelude 7.1. ? Third question, How should i set the sound system up like 5.1, 7.1 etc. ? Thanks
