Dual 5870's

Does running them in crossfire mode reduce the efficiency? I remember a way back that you would lose some crunching power by running in CF mode. Maybe they fixed it.

I can't quote where I read it, but I seem to remember someone (one person) mentioning that cross firing them for boinc was not the way to go. I can cross fire them (one is a 2mb, other is a 1mb, if that matters).

For what it's worth/not worth, my mother board is a P5W DH Deluxe.

Personally, I enjoy all the discussion, lots of food for thought. I'm going to the local Radio Shack tomorrow to set up the dummy plug just in case. I've got 235.00 is the two GPU's (one sitting next to me on the desk ) so what is another dollar or so.
