hi everyone i am not much on video gameing on the mac i am am slowly getting in to it. in my machine right now is a ati 9000 64 mb card. but i was looking at a geforce 4ti card upgrade. (a friend has one for sale for about 1500) is it worth the money to buy it for that much of a boost. and it seems like it will have minumal core image compatability. and other then games i dont know how much of an up grade it will be. thanks for the help. oh an this will go into a dual 1.25 mdd machine. thanks for the help.
