What's the price you'd be paying for them?
If you get a good deal on them, it's hard to find something else at that price. The Klipsch set has been discontinued.
As far as being a few years old, that's not really a big deal. As opposed to just about everything else computer related, audio performance is pretty well set rather than something that gets constantly improved. You can certainly do better than these computer speaker sets if you're after audio quality, but I don't really know what your expectations are for your audio goals.
If you want to get something better than these sets, I'd suggest not going with computer speaker sets. Check out the section on an upgrade path in the sticky thread and think about sinking your budget into a good 2.0 setup for now with the option of expanding it later.
