Mac Pro 4,1->5,1 RX Vega
Do the RX Vega cards need to be flashed to work with the old Mac Pros? I've done a lot of research about Nvidia cards, but I don't really know how it works with the AMD cards.

Is running an SSD from Thunderbolt as boot drive identical to having an internal drive?
On a 2017 5k iMac. Could you use NVMe to get the same speeds? And if not how big of a difference would it be? I am not willing to pay Apple's exorbitant prices on SSD but may want to upgrade to this in the future if it is in fact an upgrade over using a Fusion drive. -
