Difference between 2.16 and 2.44 GHz Left I/O board

Anyone could give me an answer to this? I couldn't find any info.
I've got the 2.44 model, and I need a new board which costs about £69.95
I just found one for the 2.16 model for only £38.99. What's the difference? Both look the same on the photos.

Ok, here's what happened, if someone has a similar problem.
I ordered the same model as the original, but they sent me a different one (obviously), which is works perfectly. So maybe there isn't too much difference.
