One of my best moves was to toss the G200 card and replace it with
multiple G450 PCI cards.
If you want to experiment more with your G200 - try moving it to a
different slot. Because of the "plu and play" nature of Windows and the
way PCI works - you will see different performance from the locaiton of
the card on the PCI bus.

The problem we have been seeing is that as soon as we open 3 windows in Vic, CPU utilization pops up to 50-60%, making for a very unpleasant experience.

Opening 3 Vic windows causes the CPU utilization to run at about 8-9%, which is great. We don't see 50% utilization until we open a lot of windows. Very acceptable behavior. Only problem is that you can't drag any of the windows over to the extended desktop on the projectors - they become corrupted. This is a known behavior and was expected.
