iMac 27" (2009-2010) supported graphic cards ?

[OCD-FREAK]

hey guys,

 

i have an imac 2009 and an imac 2010 both need graphics card replaced. 

 

can you please list all the supported graphics cards? i need the cheapest ones, the imac is just gonna be used for office stuff, so even 256mb of vram is great.

 

thank you all

Slight problem:
Typically on iMacs the GPU is soldered onto the logic board.

nope, if you have an experience opening imacs you should know that imacs from 2009 to 2011 are fully upgradable (ram , cpu , gpu)

I'm not sure how old they have to be but some iMacs use a card with the GPU soldered on it, like a daughter board. All you have to do is buy the board and replace the older GPU inside.

not really - there is literally a gpu card that you can just swap for a supported card in imacs starting from 2009 till 2011

Can you even replace the graphics card in an iMac? I unless you have the equipment for bga soldering Idon't think you can replace it.

Good luck finding a card.  You might have to salvage one out of old iMacs.

Yeah I know but they use some sort of industry standard they use for those cards that I don't recall their name. Do you have the exact model numbers of the iMacs (AXXXX)?
