Jesse Nieminen's Review from Digital Web Magazine:
"The whole point of upgrading is speed, and the OWC processor delivered well beyond my expectations. Instantly my Mac left the ranks of feeble has-beens to become an able competitor. Performance testing in all areas has proven this thing to be rock solid and FAST."
