A: No, but it'll probably look better. Halo 2 for PC will run on a DX9 card.

If this site is correct, then although you may require vista for Halo 2 - PC, you only need a dx9 card.
This doesn't sound right.
.....Well, on another page they say a dx9 card will run the game. Why would ms insist on vista an not on dx10?
I suspect that Vista will cost the same as an XBOX360 when it's released, so making you also buy a gfx card twice the price of an XBOX would limit their sales somewhat...
