Hi guys, with a z906 logitech sistem, would i feel the difference if i upgrade my soundcard from this integrated: https/www.pcgarage.ro/placi-de-baza/gigabyte/ga-b75-d3v/ to this dedicated: http/www.pcgarage.ro/placi-de-sunet/asus/xonar-dg-si/ ? What will be the difference? Or should i buy a better card to feel the difference? Thanks
