Chosen Solution
Hello! I have an iMac “Core i5” 2.66 27-Inch (Late 2009) A1312 emc2374. The computer was configured with an ATI Radeon HD 4850 graphics with 512 MB of dedicated GDDR3 memory. The card was recently destroyed and I was wondering whether the AMD Radeon HD 6970 1GB &2GB cards are suitable and compatible with my device (in order to upgrade) or advise on other cards that may be compatible? Thank you in advance.
See this guide on a replacement. But you may want to post pictures or explain in detail what you mean by “destroyed”.
