I registered to specifically post on this thread and add some more information to this. I really want to know why, I've just spent a significant amount of money to get a completely upgraded MacBook Pro 15" and if its slower than last years that's pretty ****.

Additional Information:
I picked the scores by searching the laptop on Geekbench and picking the highest Mac OS. As there are higher benchmarks with these laptops running Windows instead.
There have been mentions that it is the version of CL and GL that Mac OS runs?
Also I spoke to an Apple rep on live chat and they said that it may take time for the Mac software to catch up and use the full potential of these latest CPUs. The Apple rep I chatted too also had purchased the same 15" Macbook and was surprised when I mentioned all this information but she had some good answers as to what she thinks and where these CPUs are positioned for the future.
