YES of course but it will not run anything that requires DX10 support (still few). BUT DX10 cards are now cheap; from 8400GS to 8600GT. And you can tweak them some more (overclock).

Not necessarily. Make sure that the manufacturer says that it is compatible with Vista.
i think it should as long as it says it is compatible with vista
If you have the money, get a directx 10 card. They will always be better. I think directx 9 will work, but it won't perform as good.
yes but only DX9 games not DX10 games that are exclusive to vista.
Only if the card has Vista drivers, note there is already Direct X 10 so you are behind on the times! So you should buy a Direct X 10 card (you won't be able to play Vista only games if you don't buy a Direct X 10 card that supports Vista).
