Sound Card and 5:1 Speaker.

[cybersa]

Currently i'm having 2:1 Speaker.
So i planned to upgrade it to either 5:1 or 7:1.
What should i choose either 5:1 or 7:1?

I know that for good and true sound effect we need sound card.
So,Also planned to buy a new sound card.

Suggest me a good Sound Card and Speaker for below 6K.
Also suggest me a good Indian website to see price for Computer components like newegg etc...

If your main priority is to listen music better to buy a good 2.1 speakers like swan M10 and if you love to watch original DVDs or blu-ray buy logitech z506 5.1 speakers, buy it from buytheprice.com
