Hello, I am really interested upgrading graphic card for lovely 21.5" iMac graphic card.
There is already known post regard upgrading same model as mine but with 680M
https://forums.macrumors.com/threads/1596614/
However, there are few downside with following post
1. Losing initial boot screen (due to incompatible VBIOS)
2. TDP and power consumption.
3. Pricy! (about $500+@ on ebay)
So, I decided to approach in a different way by using Geforce 660M
There are few reasons that I decided to use 660M
1. 2012 iMac is using 660M (512MB but still same chip)
2. Low TDP
3. Cheaper (about $250)
Before I approach this major task, I am missing only one piece; iMac 660M VBIOS
I was searching in the web for few days and I failed to achieve the VBIOS.
So, if someone can please provide me the iMac 660M VBIOS, I will proceed upgrading and post results of upgrade
Thanks.
