Possible to "UPGRADE" the GFX card Early 2009 iMac NVIDIA GT120?
This is my first ever post here! I have an early 2009 imac 2.93ghz with nvidia gt120 gfx card.
I'd like to know if it's possible to upgrade this card to a newer card and have my mac still work?
I have read about possible EFI/driver issues and wondered if anyone has any experience of this or can provide me with some info on how to fix them if they occur.
The nvidia gt120 & gt130 has an unaddressed issue that apple has never fixed that causes crashes, so I would like to replace this card, with a new card and it needs to be an upgrade as this card no longer works with anything after Snow Leopard 10.6.3 without crashing.
Many thanks guys,
