Guru3d don't show ambient temps during testing for delta calculation. The Strix with hotter VRMs show 67C under load and the Aorus 71C with cooler VRMs?? The Aorus is 2dB quieter. I got the strix £788 the Aorus is 799 or 860 for the extreme and the MSI is £809 - Price wise its a no brainer.
I'm not confused, the OP asked what the difference was between the Strix and Strix OC - with those the boards and coolers are identical, they test them and mark them up accordingly
you've referenced a completely unrelated situation and said that the 1080 amp is just a failed extreme - its a completely different PCB and cooler between the two, not the same situation at all
It's a simple binning process.
My zotac amp is a 'failed' amp 'extreme'
It's as simple as that. My vanilla amp is also the lowest clocking 1080 I have had (out of four) but it reaches at least 2050 and is the quietestso this time I'm sticking!
