In a real sense, the Core i7 975XE is a slightly higher clocked 965XE with 133MHz of higher clock. In the sense of things I would imagine performance to be only slightly better than the 965 CPU as they are otherwise identical. Performance on the Core i7 975XE outshines that of the 965XE in every benchmark, making this the fastest Intel CPU to date.
