    I think a lot depends on the Motherboard, some have to run the Dummy Plugs & others not ...

    Correct. Also Crossfire removes the need for a dummy plug as the cards are then technically one unit.

    ...even though BOINC still sees and treats them as two separate GPUs.

    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.

    Off topic but, ya had to go there did ya Eagles suck, Phillies great, Flyers great, Sixers who? Elite Manning (not), Rangers pretty good, Islanders -admit to owning them? Yankees had a good season, disappointing post season like the Phillies. What about the other teams in the State of NY, Buffalo Bills - please, Mets or Mess is more appropriate. Oh, forgot the Knicks and Carmellllllllllllo and Amar'e don't play defense Stoudemire.

    Always fun to banter back and forth between the two sports cities - no doubt NY wins hands down on championships.
