I was thinking about upgrading my macbook pro to the recently released. However with recent benchmarks it seems like the early 2008 models are not significantly slower than the just release late 2008 models. The graphics card may be a little faster. The bus speed is faster, but not significantly faster. I was expecting larger increase in the cpu speeds but they are barely faster. How come? Has Intel not made much progress in the past year with their chips? scott.
