Hi Kevin,

I noted that Goli advised you that you can upgrade to i7 2600. Did you succeed in upgrading your CPU?

the maximum you can use is i7 2600k but OSX 10.8 freezes with this cpu so its better to upgrade to an i7 2600 ( I've already done this)

The 2011 iMacs have an LGA1155 socket (different from all the other models). If you wanted to upgrade the processor then you have to make shire that it has the same socket and that the TDP is 95w. The only CPU upgrades I would try and preform would involve the ones that apple uses already(the 3.1GHz or the 3.4GHz that come in the higher end 27"). The only reason I say this is because the logic board firmware might be restricted to only certain CPU's.

Hope this Helps
