Hi Calvin. I had the same idea one month ago. I own an iMac 20' 2008 2.66GHz. I've already upgraded the RAM from 2GB to 4GB. So my CPU was an Intel Core 2 Duo E8335 at 2.66GHz, socket P. And the only upgrade that was possible and easy was to replace it by a CPU with the same specifications, with an Intel Core 2 Duo E8435 at 3.06GHz, actually the one in the iMac 24' 2008, it is the same socket so I'm pretty sure there will be no problem. I managed to get one from Ebay for $90, I'm still waiting for it. I guess you have the iMac 2007, so your CPU is a T7300. Here is the specifications for this one [http://www.cpu-world.com/CPUs/Core_2/Intel-Core%202%20Duo%20Mobile%20T7300%20LF80537GG0414M%20(BX80537T7300).html|CPU-World]. You can see the CPU of the same socket that could upgrade the T7300. I think you can upgrade with all the Txxxx of the same socket, the best one will be a T9900, I'm not sure about the Exxxx because I don't know what VT, ESS and TBT stand for, but if it is possible, I'll have my E8335 remaining. Anyone can confirm this ? And if the Exxxx would work ?
