It seems that your graphics card doesn't meet the speed requirements, even though it's not on the list of unssupported card. See here: http://answers.yahoo.com/question/in...2073846AAwHM5D. I had a 9800 GT when D3 came out and it was playable, although it came into trouble in crowded areas (e.g. bridge of Korsikk in act 3). To my knowledge, that card is more than twice as fast as yours.
