Should I go for a USB Sound Card?

Hi,

I own a Dell Inspiron 6400 laptop. I recently wanted to buy a 5.1 speaker system but found out that my system only supports a 2.1 sound system. I was looking at EBay and found this interesting option of using a USB Soundcard that gives a 5.1 effect.

But what I'd like to know is, if it truly gives the 5.1 feel?

Heres the link to the soundcard page on EBay.

Any better suggestions would be appreciated!



Can anyone help me? Thanks!
