I know a few people with >130 IQ and they all have executive disfunction and anxiety problems. So yes, the best CPU doesn't help if the IO is constantly blocked.
I know a few people with >130 IQ and they all have... No, those are just the ones you know about. You know, the kind that tell people that they have a high IQ. You probably know more people with IQs > 130, you just don't know that you do because they're well-adjusted, and they don't feel the need to tell you about their high IQ.
On the other hand, almost all of my friends have anxiety, depression or executive disorders, but I know the IQ of a few of them.
