I have been looking to upgrade my mid 2007 iMac with a better CPU suited for heavier tasks. In search for a CPU that would fit the criteria of a CPU that would fit the iMac’s CPU socket type and design, I found an Intel Core 2 Extreme X9100 3.06GHZ/1066MHZ (SLB48 Socket P/PGA478 CPU on eBay for about $40. If you want more info on exactly which CPU I am talking about INTEL Core 2 Extreme X9100 in case you want a better idea of what I am talking about here. All I want to know is whether or not if the my iMac can take it as a CPU or whether or not I need to do a Firmware update beforehand to make it work. Thanks!
While the system can support the chip, I don’t think you will get enough performance benefit. You are still limited to the applications you are currently using. Make sure you are running OS-X El Capitan (10.11.6) which is the highest your system will support.
