Looking at your last screen of the panel, the card should keep the really nice core/memory clock of 157/300...
By the way: I LOVE your 'unofficial' test... there is nothing above real user experience!
do you got new info about idle-clocks with more than one monitor attached?
Many thanks for your investigation!
