I recently bought the https://www.asus.com/us/Motherboards/ROG-STRIX-B450-F-GAMING/specifications/ and, although it has onboard sound, I continue to use my SoundBlaster X-Fi Xtreme card. I have never had "surround sound" (I use a Logitech z553 3-speaker setup...https://www.logitech.com/en-sg/product/speaker-system-z553 )...but started thinking about buying new speakers on the upcoming Amazon day as rears (just literally 2 rear speakers...20$ish). Then I thought, should I be buying a new sound card? (I have a rear speaker port already) Then I thought, technically I should be asking why I'm even using my old Creative Sound card. Technically, my board is using PCI-E resources to interact with my Creative sound card that probably I don't need..or..not.(maybe my Creative card is indeed "better" than the onboard audio)...How are sound cards even measured as "better" (I checked the Creative website thinking, How do these folks even make money anymore?, and...even after browsing there, I don't have an answer except for maybe the music industry). Anyway, should I throw my old sound card away, or should I disable onboard sound? Does it really matter all that much?
