Not sure if this is related, but I have had a performance issue with dual video card/monitor setups. The setups I have tried were:

Dual Radeon 5850 cards, each connected to one monitor.
Single Radeon 5870 card connected to two monitors.

I would use either keyclone (early on) or pwnboxer (later on) to put the main WOW on one display and the rest on the second display. Whenever I was focused on the primary display, it would slow to 30 fps max, but it could run at 60 fps if I was interacting with one of the characters on the second display. The cards are powerful enough that running 30 fps was generally smooth and playable, but it was annoying to know that the minor stuttering that I would see was not due to the card being underpowered.

My current system still uses the 5870 with a single monitor, so it won't be an issue. I plan to try IS Boxer whenever I get back to multiboxing and perhaps I'll have an opportunity to test a multi-monitor setup in the future. But by then I hope to have one or two of those 3GB 580s, so that might skew the totals.
