The processor used in the 1.8 GHz and related upgrades is from a  
different chip series. While they run cooler than older processors  
the newer upgrade lacks the older version's level 3 cache. The end  
result is that the upgrades based on the newer design performs much  
slower than you would be led to believe by their clock speed. You  
should be able to find reviews and benchmarks with a little searching.
