There are still sound cards, I think Creative still makes some. EVGA has one too (for $150 I believe oof) but yeah, like the others said unless your speakers are worth big bucks you won't be able to tell the difference between a sound card and integrated sound. I have a $200 motherboard and $500 speakers and they sound great tbh, even supposedly "low end" codecs still are good. You can also get a USB DAC instead of an internal sound card if you really need higher quality.
