Radeon:
I'm upgrading my FPS2000 because the bass is too weak for my taste. Plus it seems to come and go on mine...sometimes I get no low frequency output and sometimes I get tons...too inconsistent for me.

to answer your question...if yours is a year old and it hisses, a newer one probably won't be any better.
I've heard mixed things about the hiss on the Live! values. Mine is about two years old and it hisses like mad when hooked up to analog speakers. But my ex-roommate had a newer one (had the yellow colored SPDIF connector) and he had it hooked up via analog to his stereo with no hiss. Both of us had $20 dollar monster cable stereo RCA cords too.
Personally I'm sick of dealing with the Live! crap and I've heard really good things about the Philips Acoustic Edge so I've ordered one of those. According to Insane3D, the hiss disappeared on his Klipsch PM's when he switched to the Philips card.
If you want good analog speakers, the general consensus seems to be the Boston Acoustics 4800's or the Klipsch ProMedia. Listen to both and find out which you like better and which you can afford

Its a matter of personal preference. Go for either of those.
Now comes my recommendation for those trying to decide between 5.1 and 4.1:
If you're a gamer that occassionally watches DVDs (I'm guessing 90-95% of the people interested), stick with 4.1 systems. They're cheaper, and right now there's just better sounding choices in 4.1 than in 5.1 when it comes to gaming. I'd recommend against buying a Live! 5.1 card regardless of your situation. There's no 5.1 speaker system out there that doesn't already include a dolby digital decoder (the high selling point of the new Live! cards) so its a waste of cash. You can't even use dolby digital on anything but DVDs right now. The only thing you lose using a 4.1 is a "true center channel". If you're just watching DVDs on your PC with a mere 17 inch monitor...who cares. Save the money for a real home theater
As far as games that output in Dolby Digital...this is a loooong way off. I'm talking at least 18 months, probably more. The kind of processing power you need from both the CPU and the sound card to do this in real time just doesn't exist right now. Only now are we seeing games like Broodwar and Diablo II using Dolby Surround. And its been around for more than 5 years! Save your money and don't believe the hype, Dolby digital for gaming is not a reality now and it won't be any time soon.
Jeez this is a long post...I could probably write a damn essay if I don't stop now...hope this helps you guys out.
