Flashed AMD Radeon R9 280X Mac Pro Graphics Card

Here for sale is an ATI Radeon R9 280X 3GB Graphics Card flashed with the latest firmware and is compatible in all models of Mac Pro from 2009-2012 (basically either a 4,1 or 5,1). Detailed spec for the card can be found below but i will say that  this has a single DVI, single HDMI and dual MiniDisplay Port outputs.

These are serious cards and are great for 4K video work! They also have the full 5.0GT/s link speed!

There is also full boot screen support from the DVI, HDMI & Mini Display ports (Shows the Apple logo at startup - Useful switching boot drives and bootcamp).

Complete with the card you'll get the necessary 6 & 8 pin power cables that plug into the Mac's Logic Board to provide power.

These are awesome cards for the Mac Pro and also work very well in BootCamp :)
