FYI ~ Leaning toward dual graphics cards pushing two monitors.
Wow will only render on the primary graphics card*. If you have a second GPU hooked up to a second monitor and want to run wow clients on your second monitor (connected to 2nd GPU) you will see a big fps drop from just one GPU and two monitors. What happens is windows has to push the data from the primary gpu to the 2nd gpu accross the bus decreasing fps.

I have had personal experience with this - I was sorely disappointed when I added a GTX260 to sit alongside my 8000GT with a monitor off each GPU and discovered that my overall FPS was much worse.

* I believe InnerSpace can hack around this limitation of Wow.
Thanks Jafula for a VERY informative post!! Are there any threads here or online to confirm this??
