If you're looking to get some computer speakers, those Creative are very good; I've listened to them and they sound great for what they are - computer speakers. Personally, I have (for my PC) a pair of Bose Companion II, and while I'm not really a fan of Bose speakers per se, they are great for my PC. My home sterero speakers are Polk Monitor 40s, hooked up to my Onkyo TX313 A/V amp. I also recently purchased the PSW10 subwoofer to go along with the monitors, and am very happy with the sound. I've always like the sound quality of Polk speakers, and since my music collection is on my PC and comes digitally through my Asus Xonar Essence STX sound card, it's great sound.
PolkAudio are good speakers..A friend of mine years ago told me that most American made speakers are good (Klipsch, KLH, Boston Acoustics, Polk). Japanese speakers, not so much. I have no problem buying an amp from a Japanese company, but would never buy speakers from say, Sony, for example.
Just my 2 cents.
