Due to the way wow works; 1 video card is better. See the post linked below and the threads linked in that post.

[choice] Which videocard(s)?[/url]
Having read that post, and the post mentioned within the above: If you are running Vista with 3 Screens, and 2x 4870's; do you have to screen switch every time you start up WoW in order to use both video cards? Or is this fixed in vista? (It sounded like most of the posts were talking about XP, and people were saying "horizontal span is fixed in vista")

In other words: How would you go about outputting to 3 Displays. Main screen having your main client, your extra screens having your clones.
