I have been limping along on a frankenputer that was failing every time I turned around. Thanks to Manny at Vasst I have migrated to more reliable, albeit still low power (notebook) system over the past few days.
I wanted to be prepared to to work with the 64 bit Vegas when it comes out, but folks have had a lot of trouble with Vista 64 bit migration. It appears to me that 90% of the issues were drivers for the new system and compatibility issues. That is why I chose to get a notebook with Vista 64 pre-installed; let the manufacturer fight with driver issues.
My assumption of the problems appears to have been at least somewhat valid. I am running Vegas and all of my other software very nicely without crash etc on Vista 64 at this point. No stability or misbehavior at all.
Just something to think about. Having all the hardware arrive fully compatible and checked out by the manufacturer seems to have paid off, even though I did not get a screaming machine in the process. Stable or smoking ? hmmmm
