Hmm... I am using the same system as the one used in Tomshardware tests and no matter how I tried I was not able to duplicate their results in various encoding/decoding tests. Vista is better than XP when it comes to multi-processor usage and for me who is spending most of the time doing video there's no going back. Vista is simply better. I am not interested in games they've tested so can't comment on that but I can say that I enjoy a very fast and smooth Trainz with my Vista.
