I currently have a Gigabyte DS3 rev 3.3 Bios 10 with the onboard sound (realtek). I also have an older Soundblaster Audigy (model Sb0090). I am more interested in music sound than sound for games. From what I remember when I got the card, it was a pretty good one that was optimized for music. Should i stick with the card, especially since it would take more pressure off the CPU? Thanks.
