NP.. pm me anytime you need help with the config. as for the Keyclone issue.. I found it worked well for normal use (easy to setup etc) the only stumbling block was when I levelled 5x druids and 5x mages and wanted to perform multiple AOE. keyclone allows you to do this but you have to click on the main screen 5 times rather than once and the focus kept changing in the toons windows. I did all my RAF levelling with keyclone.

as for option #3 i think it will slow your system down as runing two cards (essentially what the 4850x2 is when unlinked) in one machine over multiple screens causes an issue with direct x and slows down the rendering on the second card (some wierd fix involves changing the second card to the primary display before starting the slave instances of wow and the swapping back to the original primary before starting the main)
