I want to replace my onboard sound card with a better one. For gaming, movies and multimedia. The last time I had bought a sound card was in September of 2006, the X-Fi Xtreme Music. Because of bad drivers support of Creative I have retired it on December of 2009 and from then I was using only the onboard sound card. I want to know which is the best to select, the Asus Xonar D2X or the Sound Blaster ZX?
