'''No''' You can only use a GPU that was used by Apple As OEM so if you had an AMD Radeon R9 M290X graphics processor with 2 GB of dedicated GDDR5 memory you could put in an AMD Radeon R9 M295X with 4 GB of dedicated GDDR5 memory ''if you could find one at a reasonable price''. Also selling your old card wouldn't be too profitable as only someone with a damaged card would be a potential buyer. ''The machines are so new a damaged GPU should be a warranty repair'' . ''You'll have EFI (aka bios) and extension (aka driver) if you attempt to put just any old GPU in any Apple computer. '' ''If this answer is acceptable '''please remember to return and mark it accepted'''.''
