So let's say I want a 3.7 GHZ Quad Core computer. And I'm looking at speed. Would I say that this processor has 14.8 GHZ or is that completely unreasonable. I have read in on this and people say that it is good for multi-tasking and others say it is good for doubling or even quadrupling performance. Which one is correct and is it 14.8 GHZ?
