I have a 2.1 speaker system, as well as a Thermaltake Shock Gaming Headset. I want to plug one of them into my sound card and the other one into my onboard audio jack so that I can just switch between them through Windows instead of having to go to the back of my PC every time. Which one of these 2 audio products would benefit more from the Sound Card? I have a Creative Soundblaster Audigy. And also, so far I have not been able to notice a huge difference between onboard and dedicated sound as advertised. Is this normal?
