Any motherboard will support Windows Vista. All of those stickers saying "Vista Compatible" or "Vista Ready" are just marketing BS. The components you need to ensure are up to spec are the CPU, the video card, hard drive size, and the amount of RAM. Those are all listed under the minimum requirements for the OS.
Matt above has said Xp runs faster! Vista was not the best horse in MS stable and given a choice I would avoid vista (or install it and upgrade to win 7 or 8 ASAP!) a number of clients have had problems with vista and solved by win 7.
