    Hello there!
    I decided to upgrade my stock GT120 to a Gigabyte 6870 OC (3 fans). It´s supposed to run out of the box in Yosemite but without the bootscreen.
    Is there any way to flash the EFI to the cards Bios to get a working bootscreen?
    I found a few ROM´s but they were all for other cards like the HIS ICE-Q or the XFX version.
    My Mac Pro is a early 2009 model and runs OS X 10.10.5 and Windows 7.

    Best regards.
