Can anyone suggest a good sound card? I had an X-Fi Xtreme Music, but now it is not working properly, so I want a new one. I am not technically aware about the sound card components and seek your advice on it. For me X-Fi Xtreme Music is also good, but my budget does not allow me to get it, so I need your help to find cheapest and best option. My budget is around $70-$80. Please suggest good one.
