Hello everyone, I have an interesting question: Currently I'm running my Mac Pro with two GPUs: The Apple NVIDIA GT120 (so that I have a boot screen) and an EVGA NVIDIA GTX 1080 FE (just using the native drivers) I know one easy solution for me would be to send my GTX 1080 to MacVidCards.com to flash the EFI (I really wish I could just do it myself) but what I would like to do is buy the Apple Radeon 5770 (or 5780 or another Apple card), insert it into slot one, and then make a PCI-E EGPU enclosure for my GTX 1080. That way I could use two cards, create some breathing room in the chassis, and I could have the freedom to remove the GTX 1080 and put it in a TB3 E-GPU to use with my 2016 15" MacBook Pro. I'm also trying to make an easy setup for me to sell my Mac Pro once the redesign is officially released and we see what that will be all about. Had also considered just expanding my PCI-E slots but I have had a hard time finding out how to do that and I learned that the two x16 slots are already reduced to x8 when both are in use. Basically I want to use an external PCI-E GPU, what would be the best way to do that?
