I am a fan of multi-monitor systems...
In Vista support for multiple monitors is slightly more restrictive, here's
a summary:
Multiple monitors attached to a single card - no problem
Multiple monitors attached to multiple cards with the same driver (which
normally means the same chip set family) - no problem
Multiple monitors attached to multiple cards with different drivers - no
support for Glass
