My .02: I believe the majority of problems with Vista 64 were driver problems - which generally means hardware issues, not software. That's why my music computer is still on 32 bit, even though I could dearly use the extra RAM 64 bit provides support for.

And that leads to the other point: If you upgrade to Vista 64, you can throw a lot more RAM at your renders. That should work wonders.
