Do we use only ten percent of our brain? Yes!
The first question is how much of our brain do we actually need to function. A French tax official that suffered from hydrocephalus had only about a quarter of his damaged brain left, and that part was damaged. He clocked in at 75 IQ, managed to hold down a job at the tax office, and had a wife and two kids. (Links below)
That being said, if he had four times the amount of brain matter, could on have an IQ of 300? Possible, but how can we get to IQ 1000? And yes, I know there are some problems with the IQ concept, but please bear with me.
How about adding perfect memory to that mix? Jill Price has a memory, that won't fail. Add in the abilities of acquired savant syndrome such as music savant, art savant, and mathematical savant, and yeah, we only use ten percent of our brain provided we can get this to work.
Ah, but can we harness one hundred percent of the brain? We haven't yet and unlikely to. But in the future with nannites we can. Something like using nannite coprocessor to enhance the brain's function, some refined electronic brain simulation, and perhaps increasing the flow of nutrients and removal of wastes (including heat) might work. IQ 1000 here we come.
So what would IQ 1000 would be like? Not forgetting names, important stuff, and you know, when the next day you realize that you should have said some great idea or one-liner. You did, and kicked yourself for not saying something even more awesomely brilliant. New ideas and increased creativity will be the norm.
Never underestimate the potential of the human mind.

Oh, wait. We are potentially only using ten percent of our brain.
