recently i bought logitech z623 2.1 thx speaker. so i was wondering do i really need a sound card or usb dac? i am not a hardcore gammer. i love listening music. my mobo is really old(gigabyte ga-p55-usb3). so i thought that the onboard realtek sound is not enough to produce good quality sound as compared to the speaker. when i turn the volume all the way up in my speker i can really hard the hissing noise comming from my onboard sound. so my question is that really do i need a sound card or any external dac to improve the sound quality. if really i need a usb dac or sound card then pls suggest.
