Honestly waiting three months for a card that's been on the market since 2009 is ridiculous to say the least. Not to take over this thread. Please help put pressure on Apple, answer the poll on this thread: https://forums.macrumors.com/threads/1036414/
Okay but it hasn't happened in a very long time, and especially not since they switched to intel. It is really sad, you would think that having the same platform as PCs would make it easier to bring video cards over. Yet it is still hard to persuade manufacturers to flash the cards for EFI.
Stupid BIOS, it's so out of date and needs to die already.
