Sexy Card, im still hoping on getting one. Did you have any fitment issues like the techpowerup review ?
It's huge, much bigger than than a reference 7970. Will not fit inside most ATX cases without some elbow grease and a dremel. One more issue (maybe it's system specific) is the inability to tweak the voltage of second gpu. MSI afterburner can tweak voltage of the first Tahiti chip but not the second (/stuck at 1.17V).
