I think the 2 responces form Smooth and EvoX seem pretty consistant with what I've found searching on this forum and a few others. Some it works great - others have issues. In general I don't think anyone has been able to point to what the issue is.

@EvoX - have you tried both with crossfire enabled and disabled? What OS are you using as well. I'd suggest Win7 if you can.
I'm using Win 7 Build 7100 64-bit. I'm not sure if later builds or RTM has had any changes that would affect this or not. Initially, Crossfire was enabled as per default settings and only one monitor would get signal. I disabled CF and managed to get all 3 but couldn't get around the FPS loss whether running 2 of the 3 monitors from the primary card or the secondary. I tried 3 monitors back in June or July, and wasn't terribly upset that it didnt work since I was already prepared to split the team across 2 PCs. Maybe on update Tuesday I'll spend the morning downtime (my usual after-work play hours) downloading RTM and grabbing the latest Catalyst drivers to see if anything has changed. Thanks for the input.
