Solved Gpu Upgrade For 20 Imac Mid 2007 Imac Intel 20 Emc 2133 And 2210
Chosen Solution I have a 20" iMac (mid 2007) What is my upgrade path for the graphics card ? I have a ATI Radeon HD 2400 XT with 128 MB of GDDR3 SDRAM in my system now. I would like 512 MB at least but 256 MB will do the job. Apple only offered two graphics cards for this series: 128MB ATI Radeon HD 2400XT - Apple P/N 661-4440256MB ATI Radeon HD 2600XT - Apple P/N 661-4436 So you could swap it out....
