Once again, I am not in a position to be throwing off suggestions or fact, but I believe if you are using subpar speakers with compressed audio, upgrading to a better sound card will do little good. I believe the Logitech Z-5300 are rather powerful (if I recall), so you might.
I am somewhat of an audiophile wannabe. I have a Xonar, higher-end headphones and listen to everything in FLAC lossless. I did notice a substantial difference between the on-board sound and the Xonar in listening tests, though I didn't really expect to.
There are a few songs in particular where I really notice the difference, especially with regards to instruments and voices. Johnny Cash's "Folsom Prison Blues" is one example where even older recorded music sounds so much better. He opens with "Hello, I'm Johnny Cash", and despite being so damn old, it sounds so damn good.
Two other examples are Barenaked Ladies "This Old Apartment"... with the Xonar and good headphones, the song is pure aural bliss. Then there is Social Distortions "Another State of Mind" which opens up with tapping of cymbals... and it also sounds truly robust and realistic.
I am no authority to compare speakers, however. My Logitech X-240's aren't that great for the sake of comparisons.
