I second the above statement. The fact that you didnt describe your power supply means you probably dont want a card that needs extra power.
The card above is at the top end of cards that wont require a power upgrade so would be a good deal. The 1 gb version is available for nearly the same price.
or you could consider this one: http://www.newegg.com/Product/Product.aspx?Item=N82E16814133279&Tpk=9800%20ee
Its at the top end of your price range, but I think it would be a little bit better. (most 9800s require a power connector, but this one is nerfed so that it doesnt)
Any one else want to jump in and tell me if im right? I am considering buying this card too.
