Better than what? Your question isn't the easiest to understand but I'm thinking you are asking what soundcard you should buy on a budget of $100.

Tell us your system specs, especially your motherboard. Integrated sound these days is high enough quality that you would not notice a difference with a dedicated card. Most even support up to 7.1 surroundsound speakers. I doubt you would notice a difference, especially with those speakers.

mx5021 is pretty good, u would find a difference, but that also depends on how good the card is too, u cant jsut say, you wont find a diff, with THAT speaker, it also depends on THAT soundcard, try the ASUS range, ud probably find a difference from an onboard, even with a £60 pound speaker set.
