I have the exact same setup except my video card is Geforce 2 GTS and my memory is crucial. I chose the GF2 GTS because of better Win2K ( whenever I will start using it) drivers and it's just faster for the games I play. My friend has a Radeon and its great if you use the features, however I don't so it would be a waste. I like to refer to the Radeon as the card for the person who needs the features and likes to casually game. I could be all wrong though .
