Warhammer Online and Vista compatible?

Does anyone know if Warhammer Online is compatible with Vista? I am going to buy new Windows OS, very soon. For that reason, I want to play the games on it. I have heard that WAR is supported in Vista, but I do not know if that is true, or just another lie. I need help from you people and game gurus to tell me the answer to my little question.

First, I need to ask you why are you buying Vista in the first place. It is still not good enough. Especially for players, because it has bigger system drain than XP. But, if your mind is set, than you can buy it. More or less every game will work on Vista, and if you have high-end configuration, you are going to be very happy. Vista is meant to be a gaming OS, so it will run every new game at its best. Warhammer Online and new windows OS are compatible, so enjoy playing it.
