    Yes. Time Machine considers your new logic board a new computer, which it is, essentially.

     

    Choose "Inherit Backup History". That is what you want to do. Your old computer is gone as far as TM is concerned.

    ... as a for instance can i /recover/ data from the existing backups?

     

    Yes. Here you go: http://support.apple.com/kb/PH11344

     

    You’re prompted to specify whether you want a new computer to inherit a backup if you do any of the following:

    • Use Migration Assistant to transfer your settings from an old Mac to a new one.
    • Use Migration Assistant to transfer your settings from a Time Machine backup of an old Mac to a new one.
    • Clone the disk you use to start your computer, or physically move it from an old Mac to a new Mac.
    • Replace your computer’s motherboard. <-- that's you

    ... i am supposed to click "inherit backup history" even though "create new backup" preserves the old computer's backup history?

     

    Yes. If you were to choose "create new backup" the existing backups would not be affected, and would remain accessible only to the old computer (old logic board, in fact).

     

    Conversely, if you choose "inherit backup history", your "new" computer will be entitled to use the backups that exist, and add to them as if you did not replace your logic board. The consequence of this choice is that your "old" computer (old logic board) will be unable to use the existing backups.

     

    Does that make sense?
