The interesting thing with Vista will be the 64-bit application. I'm wondering if that will have a positive effect on DAW performance or not. Surely the removal of the 4GB RAM limit can only be a good thing, at least. For the most part, that's the only real benefit of a 64 bit OS on a DAW; being able to address more memory. Many audio apps run 64 bit internally nowdays anyways on either a 32 or 64 bit system. ew
