YesIf i install a gtx 970 (non mac) i loose the boot efi screen.
is it possible to install an older gpu just for the boot efi?
gt 120
gt 8800
gtx 285
those are popssible gpus that come to mind but im guessing not compatible with yosemite?
Yes
But if you don't have a Mac you don't need an EFI boot screen. If you need a boot loader for Hackintosh that's another story.
Thats what I thought....is there any other solution? 8800gt 7300gt?Issue with GT120 shows up in Windows. No driver for both, it's an either/or.
