An external audio interface or DAC will be 100x better. That audio card won't be any better than the on-board audio.

Some of them have poor stability. I gave up on a Sound Blaster Audigy RX after it caused random crashes on two different Socket AM4 mainboards. I just got a 10 metre optical cable and a cheap DAC next to my reciever.

I suspect the industry is in a tailspin; the last players standing really don't have to give a **** because the alternatives are onboard sudio or $$$$ pro cards.
