Yep, it's a very slick machine... Pleasurable and fresh to use, and a definite improvement in performance noticable between it and the single-core dual. How much of that is attributable to the flakey logic board is open to speculation, however an imrovement is an improvement no less. It dissapointed me at first that it turned out to be DC not DP (as advertised), as I realised all of my RAM etc wouldnt work, and I need to find an ADC adapter to continue using my Studio Display, however it opens me up to some sweet hardware I couldnt use in the old one!
