Klipsch Computer Speakers

Currently I have Realtek HD onboard and I think it’s broken as I often hear hissing when listening to loud volumes and my right speaker keeps going out (doesn’t do it on my other computer)

So yeah, beside that stuff I’ve been meaning to get a soundcard anyhow.

I’m looking for a cheap soundcard, nothing extreme, that will sound better then my Realtek HD and make my headphones I’m geting (Sennheiser HD485) Sound good.

First off, a few noob questions:

Does speaker affect the quality of sound if you plug your headphones into them? I’ve always plugged my headphones into my speakers. (Are you suppose to? or do you plug the higher-end ones directly into the computer?) I tried that with my cheap 10$ pair of headphones, and they sounded much better plugged into the speakers. ( I have a 90$ Klipsch pair of speakers, but I can’t seem to find the brand name. )

And can anyone link me to page where I can get help on installing them myself

and recommend some good 50-70$ SoundCard’s omg5charslef

first of all dont send such a big question…….acually i dont know the answer……..sorry…….
