I took a brave step and rebuilt my desktop machine with Vista ...

The 3-monitor setup worked with my Radeon 9250 and 9600 cards under Vista with the Windows-supplied driver but this driver is outdated (and Vista kept blue-screening). 

Adding a new ATI-supplied driver meant that the 9250 no longer works as it's old technology.

The simple solution is a new card but finding a new PCI card that has an up-to-date ATI chipset is ... difficult.  I looked but the only ATI-based PCI cards are 9250 based.

I want to stick with ATI to keep support simple for multi-monitor stuff.

If I can't find one then it's a new motherbaord with PCI-E ...

Any ideas?
