Well nearly - see the 4 page article on why sticking with XP and a few addons is possibly best ...

However, users with dual-core PCs may notice a performance boost with Vista when they're multitasking, because Vista can take advantage of dual cores to run separate processes, something that XP can't do. So if you have a dual-core PC and you frequently run multiple programs simultaneously, you will lose the performance improvement that Vista can bring.Even NT4 supports multi-CPU systems. And multitasking isn't done per-process anyway, it's done per-thread.
Microsoft also claims that multimedia will run better in Vista than XP because Vista can give streaming audio and video priority over other processes so that they won't be interrupted.That sounds a bit silly as well - you can already manually (or with whatever tool) raise your media player process priority.
Perhaps for the media portion they mean they can use QoS to allocate more bandwidth to streaming media. Increasing process priority on the player wont do this for you.True enough, and there could be some advanced in kernel-streaming drivers as well (which has nothing to do with internet streaming btw), etc. There's nothing stopping QoS on XP though, and iirc win2k supports it as well - just a matter of making the media player utilize it. Oh, and the rest of your networking equipment.
