90% of the applications out there are PowerPC only currently. That means that rosetta has to translate the PowerPC calls to x86. That takes a lot of CPU Power and memory. For apps like MS office, you're not going to see much of a difference. For CPU intensive apps like photoshop and games, there is going to be a major slowdown until a intel version is released. The good news is you'll see an equally major speedboost from a PPC mac.
