Hi  here is a  Mac metal compatible Flashed  Sapphire GV-R928XOC-3GD (rev. 2.0) Windforce. This card works great and has a full boot screen for Mac  users who require a boot screen. The card needs two power cables to run one six pin power cable and an eight pin cable to operate. I have attached pictures of the card working in a 2008 Macpro 3.1 running Catalina  with a proper boot screen. The card was made based on the R9280X architecture and is listed as such in your Mac. 3 fans that are quiet and function as they should. Also Dual bios switch and switch position 1 is stock Bios for PC booting if needed . Position 2 is where the Mac EFI is and I have left the card  in that position . The GPU is working great and does what it should . Just so you know I have just used the DVI output as that is all I have for a monitor in my lab. Please read the freight part below in my auction so you are not freaked out by the freight. 

 I will not sell to Mexico as I  have had too much bad luck with that country and people buying from there. 

We  are in CANADA and  the buyer is responsible for all freight duty , customs brokerage and taxes.  Just want to be clear as  I  get lot of email about freight and  " oh I did not know you were in Canada" I though  Saskatchewan was part of Alaska  ,lol"

 

Feel free to put in an offer on this Sapphire R928X OC  Flashed for Mac 3gb. Please no insulting ones as I am too old to deal with that . We are good people  just trying to make a living and we are not a big box store.

Canadian Buyers Must pay GST
