don't know the conversion to Pounds, but I started of with a MadDog Predator 5.1 card (about$25 USD) that was better than the onboard I had at the time, but that was AC97 audio. I am not familiar with the onboard on your mobo, and would hate to say for sure. Also, check out Turtle Beach cards. Economical, good features for the money. I have a Catalina, supports up to 7.1. It was about $50 USD. (I'd give ya the MadDog for the shipping,if you like-if the shipping over there isn't more than you'd pay for the card)
