I've just started multi-boxing myself, on a Mac, and I'm running 5 shammies. My hardware is a Mac Pro with NVidia 8800GT, 30" monitor for my main window, 17" that shares the 4 slaves. I use the freebie clonekeys for keyboard multiplexing, and the usual assist macros. This config runs 5 instances of WoW just fine.
Clonekeys does seem to be slightly buggy, I have cases where keypresses seem to get dropped. From time to time a key press will go to 3 of the slaves, but not the 4th, so I find myself spamming casting keys. Also, when telling it which apps to broadcast from, make sure WoW is not in the middle of a loading screen, or it's likely to freeze up. For the most part though it seems to work fine.
Zoning into Shattrath is my biggest problem; massive hard drive thrash and consequential lag when I do that :(
Hope that helps.
