CPU upgrade 2.0GHz to 2.8Ghz ( C2D Extreme X7900 )
Well, I have an iMac 20'' ( ver. 7,1 - Late 2007 ). My CPU is a T7300 @ 2.0GHz.
Can I upgrade the processor to C2D Extreme X7900 @ 2.8GHz ?
It's all ok! :-)
I work with iMac 8 hours per day and don't have any problem!
It's totally recomended to change the CPU ! I install Lion and works perfectly.
