Video Card Replacement from HD4670 256 MB to HD6970 2 GB
Good morning everyone! I would like to ask a question.
I have at home a 21.5” iMac Mid 2010 with a AMD HD4670 256 MB graphics card, and I have a second graphics card a HD6970 2 GB.
Is it possible to replace the 4670 256 MB to HD6970 2 GB?
I have space because I installed an SSD and removed the DVD player drive. If possible will work normally or need to install new ROM and If possible will it work normally or will you need to modify the ROM and EFI boot screen mode?
