In fact if you drop a 100Ghz version of any processor on the market into a current system, the performance increase would be less than 10%
Thats where I am anxiously waiting for optical mobo pathways and optical data through put on chip, of course there are issues like cost and wave devices to take it from light to electron, but Intel has done some great work in the field as well as others, its still taking so long to get past current materials trends to something that could even allow bus and mobo through put to operate at cpu core speeds, that would be a huge perf boost on current technology.
