Asus Xonar DGX: Yes or No?

Useless if you only want it for gaming.

I used xonar dg it does not remove the noise

These days you're better off with onboard sound than a budget card.
Save the extra $$$ and get yourself some games with it.

audio card is very spesific stuff, it cant give u fps or something else. it change sound a little
i have ASUS Xonar DX
will i sell my card now and return to realtek - no
but, will i bue Xonar DX card now - no

so, if u want some changes - u must try it
