hey mo I found a review of the lead tech for you
The Leadtek Winfast 6X offers a lot of options for a low cost card. Music quality was good and sound was reproduced through all four speakers. Positional sound in games was also good and didn't result in a large performance hit. DVD performance was adequate, but sound was not as sharp as the Philips cards tested. However, taking into account the price of this card at ~NZ$80 you can't really go wrong if you are looking for an entry level or low cost feature rich card.
