Brand new cards, pulled from new computers !

For the very first time professional graphics card for Mac Pro 3,1/4,1/5,1 exclusively from MacVidCards Europe. Features the latest Navi23 chip from the RDNA2 family and 8 GB of GDDR6 ECC memory.

Only our modified cards are able to work normally in these models. Standard PC cards won't even boot inside Mac Pro.
