music can only get as good as your speakers anyway. so unless you spend 400+ on them (and you shouldn't lol) it will never matter what sound card you have.
the only real sound technology to follow right now, at least for gamers, is how many sound effects can be played at once.
older cards max out at like 64, better ones at 256. but that many can be spammy and not even used by games lol.
have your games render sound with hardware instead of software
