LOL... only 2 people commented on the ATI 1.17s. They don't work in Vista 64. There were reports that running the core in compatibility mode for XP SP2 worked. And yest it ran but my 3870s took a huge point hit. I went back to the 1.1.0 for now. It's reasons like this I always rename the old core rather than delete.
