Need Your Help Guys

Hey

I need your Help,

I bought 2 speakers to connect to the Flat Screen TV I bought.

And now I want to connect the computer to the TV, so I could hear music from the computer on the speakers that connected to my receiver and also that I could see movies from the computer on the TV.

First of all, I need your help to find a good sound card to my computer.

Can someone please find me a good sound card?

from this site: www.newegg.com

And also I do I connect the Video from my computer to my TV?

Thanks Guys
