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.MacBooks iMacs iPods AirPorts, OS X Mountain Lion, 27 years Apple!

so, can i please ask you if the /data/ that is already backed up to the Time Machine is affected in any way? i mean, 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

ai. i am feeling very stupid today or i am dealing with too many computer issues.
i have a new motherboard which means it thinks i have a new machine. from the url it appears that /adding/ backups to the existing backups is not possible?
i mean, the last two paragraphs here are very confusing. is my case the first case or the second case or do i have an option here?
"If you are replacing an old Mac with a new one, and want the new one to use the backups from the old computer, click Inherit Backup.
If you plan to continue to use your old computer, click Create New Backup to preserve the old computer’s backup history and start separate backups for the new computer.
i am supposed to click "inherit backup history" even though "create new backup" preserves the old computer's backup history?
for some reason i am not understanding the options here but i THINK i want to try and retain any files that may have been changed or accidentally deleted on the computer so i can go back and retrieve them (if this is possible of course). AND if it isn't possible shouldn't i be wiping the drive clean and starting again??

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?

for some reason the wording in the tech article had me tripped up a good bit.
