I have a Mid-2010 21.5" iMac and I want to upgrade the 3.06 i3 CPU to a 2.5GHz i5.

Why not an i7? Because I just happen to have a Core i5-2400s on my desk that I took from a Mid-2011 iMac and I'm wondering if it's possible to upgrade the processors or if they're soldered to the logic board like some other iMacs.

I am going to upgrade my 3.06 i3 to the i5 680. I researched it and it seems that you need to use a processor that was used in the iMac originally by Apple. The i5 680 is the best CPU used in the 2010 21.5 iMac. I have read a lot of reports that indicate that that CPU works in the logic board, but other have not worked. I will be doing it this weekend.

I don't think upgrading to a dual-core i5 is worth it. If I were you, I would go for a i7 870, which should work fine according to this article:

Form a dual-core to a quad-core with HyperThreading is a huge improvement.

The article you link to specifically states that i7 870 has proven not to work as a upgrade for "iMac "Core i3" 3.06 21.5" (Mid-2010)" likely due to its higher power requirement (95W as opposed to 74W) and that I5-680 is the fastest possible upgrade.

OP's original suggestion with Core i5-2400s, will not work either, because it is sandy bridge generation chip (2011 iMac), not Nehalem.

Sorry I didn't read carefully. Then you are right, i5 680 is the fastest compatible option.

that's an odd decision. Why not just use the ATI Radeon 4670?

I've got the 2.5GHz i5, 24GB RAM and a 512GB SSD installed and it's pretty fast, but what about the video card? I'm not a gamer, but I do a little iMove and usually have anywhere from 5-20 YouTube tabs open in FireFox.

By the way, it's a Mid-2011 now because I replaced the entire Logic Board.
I know this is an old thread, but I wanted to follow up, specifically.

Did you upgrade the entire logic board because the CPU upgrade didn't work? Or did you simply get a good deal on a full logic board that included the CPU??

Yeah, I also would like to know.
