neuroscience - Is there a correlation between total neurons and intelligence?

Thanks for looking.

First off, I am not a biologist, just a curious layman, so I apologize in advance if this isn't a "good" question. Please don't downvote me into oblivion.

I read today that the human brain has about 100 billion neurons and that got me wondering: is that number pretty standard for everyone or does someone like say, Einstein, have many more neurons than this daft poster.

Is there a correlation between total neuron count and intelligence, or does intelligence depend more on the way neurons are used--or some other factor like previous experience--rather than their total count?

There are two very valid points-of-view posted as answers below, but it sounds like we simply don't have a solid answer to this question at this point in time, so I hesitate to select a "correct" answer.
