[QUOTE="MikeM, post: 1212881, member: 39238"] From a PC perspective, This kind of upgrade is only possible if the BIOS contains the proper microcode for the new CPU. Different class Processors (Clarkdale, Lynnfield, etc...) have different microcode requirements that are normally added to BIOS updates for PCs allowing them to use newer processors so long as they have the same socket and voltage specs supported by the motherboard. Macs on the other hand are not designed with CPU upgrade in mind and their firmware (EFI) is most likely not updated with newer microcode unless they use a universal binary across multiple mac models (and even that dosen't mean it will work). An I7-870 is close to $300. Make sure that whatever retailer you are going through has a return policy that accepts opened hardware back for refund just in case. -MikeM [/QUOTE]
