Since when does SLI not work on Vista? I've seen many MANY systems running SLI on Vista Home Premium (unless you were only referring to 64bit Vista and SLI). I've actually never even heard of SLI issues with Vista up until this point. I may not be Microsoft MVP, but I've been around many gaming forums and the like with many rigs that are capable of this. Not to mention many custom builders (iBuyPower and the like) offer SLI rigs with Vista. Perhaps I missed something and I'm sorry if I did. :s
