What is a good sound card out there?

For under 100.00

I'll mainly be using it for games but I will listen to music as well. I mainly won't a sound card that will let me listen to some good bass and I would like it to have some thing like eax speaker testing that sort of stuff.

I put this question in the wrong form before comming here.

My current sound card is a sound blaster audigy 4 and it works with 1.2 1.4 and 1.5 also 1.7 and inbetween ones as well anyways my issue with the one that I have at the moment is this.

It works for a while and then out of nowhere it will like delete its self and there would be no sound well there would be sound but I couldn't run a speaker test or get drumbs and bass on like I used to so I would tell the install dis to repair it and it would but then it seems a few days or weeks I'm not sure wich it would do it again and it is driving me batty. So that is why I'm wonder what is the best card for that amount of dollars.

Also I'm willing to go over that amount just a little bit but mainly what I want to do is check out some sound cards read up on them and see if any stores around here has any.
