i have recently purchased a 32" tv with a dvd player with 5.1 speakers bundle. I'm connecting via hdmi from my ps3 console to my tv. and rgb component from my pc to tv. But i'm only using my built soundcard from my pc to the dvd player(auxiliary). I would like to hook up my ps3 console, my pc to and my dvd to a 5.1 sorround sound speaker experience. What to i do? Do i buy a high end sound card and hook up everything to a receiver? any suggestions? what sound card? receiver? My budget is around $500-$600 is dat enough? thank you
