Actually, i was looking for this information as well since a long time ago, but unfortunately someone managed to add a comment to my Document.
Yes you are right, it is defintely a good idea to know which board offers the best performance when using Core I7 CPU.
Anyway, I did some benchmarking a few months ago, i was hoping for someone to test other boards and post a comment, but no one did that.
Do let me know if you managed to know something or even better if you have another board that uses Core I7, do some benchmarking and let us know the results.
All the best,
