I have my old i5-4570 bench nearby, if it has anything useful for Vista, let me know.
Got the specs (datasheets) on Intel Series 3 chipsets, well, that's true, but from what the community says over on MacRumors, there is no need to panic at least on P35 chipset, which is used on my GA-P35-S3G mobo.
But all those Intel ME or AMD PSP things don't bother me much as I don't process any highly confidential or top-secret machinery things on my home computer. If I did, then I'd care cutting/disabling this out. Fingerprinting? To be fair, I have some experience over web developing, and to my perspective, fingerprinting is barely possible to avoid unless you visit websites that explicitly don't run any analytics through JS or cookies.
