These were released about the same time as the first klipsch set. Was a lot of talk around the web about which was a better set - basically, they both ended up being about even, with the Cambridge set being slightly better for DVD / movie watching (true 5.1) and the Klipsch set being slightly better for gaming (plus the Klipsch would play at much louder volumes)
I got mine a while back and have loved them since then. Used them with my TV / Home Theater for a brief bit and enjoyed it, but then hooked them up to the computer. Works great and plays plenty loud for mp3s or gaming. Plus there's dual inputs (analog/digital) in the back, so if you're creative you can have them hooked up to two computers and switch back and forth easily. Note you must have a live! soundcard to do digital I think.
$90 is a steal.
