    I have a 2006 Apple Mac Pro 1,1 that I have upgraded the CPU's to 2x Intel Xeon X5355 SLAEG CPU's and upgraded the ram to 11GB. I have also flashed the firmware to the 2,1 firmware and installed Yosemite with SFOTT. I have also upgraded the Graphics card to a Zotac GTX 570 1280MB . I have been using it in this configuration without issues for a long time.

    Im just wondering is there anyway to flash the card to a mac compatible EFI and have working boot screens. also I'm using 2 monitors and would like to add a third what is my cheapest option. I do still have the stock NVIDIA GeForce 7300 GT.

    I am also trying to find the easiest way to upgrade to El Capitan on the Mac Pro.

    You ask is there anyway to flash this card, there just might be, maybe check with MacVidCards as they offer a flashing service for many cards including ones with the Nvidia 570 chipset.

    The model they offer flashing for is the 570 HD not the standard 570
