It's really just shocking how you spend good money on a (then) new card and when you look at it years later, the factory thermal grease looks like someone glopped it on literally with an ice cream scoop. Also, I have the cooling unit from another MSI 280X in reserve, in case the fans burn out. It's actually from my first 280X, but I tried to remove that damn resistor for the full 5 GT speed and in doing so the card died somehow. And then Apple comes along and resolves the issue with a firmware upgrade out of nowhere.. What's funny is that I'm running BOINC on a Mac Pro 5,1, hexacore CPU, Mojave 10.14.3, and the GPU BOINC work units take only 17 minutes to process.. on an 8-core iMac Pro running 10.14.3 with a Vega 64, the work units take 20 minutes to finish.. eh?! Somethings wrong with this picture, but it aint on the old 5,1's side.
