Hi there, thanks for visiting the store! For sale is an NVIDIA GeForce GTX 680 2GB that supports EFI macOS boot screens for the Mac Pro 3,1 through 5,1. The graphics card you receive may be branded by ASUS, EVGA, PNY, Gigabyte, or Zotac (flashed). Please confirm that you have room for a 2-3 slot graphics card. This does not effect the graphics card’s performance. This is a great option for those who would like to update to more recent versions of macOS, such as High Sierra, Mojave, Catalina, Big Sur, Monterey, and even macOS Ventura! This card works out of the box without any software required! When purchasing, please make sure that you have the proper PCIe cables to power your graphics card. I will tell you if you need 1x 6 pin+1x 8 pin or 2x 6 pin.
