So I've never owned a dedicated sound card and I'm not sure what I'm missing out on. Currently I run a digital audio out via HDMI to my receiver (Sony STR820 7.1 @110W per channel) via my 560Ti. I never run analog audio, either through the front headphone port or rear outputs. So what am I missing? Is the digital audio sound from my gpu better/worse than analog onboard? Especially since it's going to a home theater receiver, would it make a bit of difference if I were running a dedicated sound card to send the digital audio signal(toslink)? Also, if you think a dedicated card is worth it; please provide a suggestion. Thanks!
