The 285 is two 260's bolted together - two video cards = bad for dual boxing on one machine under vista as well as XP. You will need to launch wow using that 2nd video card as the primary device - which I'm not sure if that is possible with the 285.
You're talking about the 295 now. The 285 is only a single GPU card just like the 260, albeit more powerful.

And as stated, blame XP for not being optimized for dual-view mode. :< Basically it cuts your FPS in half on the second monitor.
