Man, Klipsch is still the best you can get for PC sound. I spent $300 on one of the first sets of speakers they made for the PC almost 6 years ago. Best purchase I ever made. To my knowledge they do (or did) have a 2.1 set, but it'll be $150-200 probably. All I can say is you won't regret it, except maybe not getting 4.1 or 5.1.
