EDIT: I read an interview with one of the ATI Catalyst Driver developers stating that on the Vista OS There is a limit to how many frames can be pre-rendered ahead of time and cached for faster rendering of the upcoming frame. The problem with that is that the number is only 3 frames, therefore the amount of scaling from 3 to 4 cards in Vista is basicly none. To make things worse he admited that they have yet to find a successful work-around. This was added to vista because of carless game programers in the past were using very large numbers of pre rendered frames that in some way could cause series problems (The type of problems was not mentioned). However a 4th card is able to take the role of handling AA and AF and other filtering.

based on this I would guess that XP would be the OS to use if going for 4 way Crossfire.


I read somewhere that XP can only handle 2 GPU's max, and would not be able to use a 3rd or 4th card. Would be nice if this is false, but I don't think it is.
