IQ is an extremely narrow, extremely limited metric that only measures very specific traits. I have tested at an extremely high IQ and it's done jack shit for me.
Using the recall/etc to enhance my learning about things that interest me (primarily what makes people tick and how to apply some of those concepts in software) has probably helped, but I'd argue the books I've read are far more important and far more valuable than IQ. If you make a habit of learning you learn and can do whatever you want. If you don't, "intelligence" doesn't do anything for you.
