My system currently has an ATI 9600 AGP, 128 MB video card in it. According to the VISTA advisor software this card will run under Vista but I have been told that it will not be able to do DIRECTX 10. I would like to upgrade and get a card that will run the high end version of VISTA but I don't know the first thing about Graphics cards and which one is better than the other. Best Buy has a ad in this week for a BFG GeForce 7800 GS OC with 256 MB of memory on sale for $249.00 and I have no idea if this is the right card to invest money in or not. I would REALLY like to receive recommendations as to what AGP card will run DirectX 10 and run really well under VISTA.
