    I have a 20" (white) iMac with a bad logic board. The part number on the board is 820-1888-A. I'm wondering if I can upgrade it to a Core2 when I replace it? :confused:

    hmm that should answer your question

    but 2.33 ghz are the maximum for core duo to core2 duo upgrades , hardly worth the effort and risk and money if you need a new logicboard first to even get the iMac working again, because logicboard and processor together will set you back more then a used iMac with core2 duo will cost you

    No. Being able to install Lion when it comes out would be more than worth it, the 20% mhz:mhz performance improvement aside.

    A core duo imac is almost 5 years old I think.

    As the other user stated, is it worth the price to even try to do that type of upgrade just to be able to run 10.7?

    if you want lion it would still be cheaper to sell the working bits and get a core2 duo iMac , we are talking about a iMac with a broken logicboard thats out of any warranty , not just processor upgrade here

    the price for a logicboard and processor upgrade comes to a good $900 + and in my book thats not worth it to spend in repair costs if you could get a refurbished iMac 21.5 with i3 processor with full apple warranty for just $100 more

    and it looks like Lion can run on a core duo as found on the web with a screenshot of about this Mac
