If I was spending this much money on some PC speakers:
a) Almost definitely wouldn't be Bose. SO overpriced for what they are - really not worth the money in my opinion.
b) I'd be considering what you want out of such a system. If it's just to sit back and have decent sound you can get away with spending a lot less!
c) Instead of throwing around model numbers on forums I'd actually be going out and listening to the things! What my ears might find fantastic yours might find awful (and vice versa.) If you want a lot out of these speakers and really want to enjoy listening to them, you need to, well, listen to them to check whether or not you'll like them!
