Some studies can't demonstrate differences beyond 130 (which is different from showing that they don't exist).
Most studies, however, show that these differences still matter. Look for papers from the "Study of Mathematically Precocious Youth" dataset, in particular "Ability Differences Among People Who Have Commensurate Degrees Matter for Scientific Creativity" by Park, Lubinski, and Benbow. It shows a very strong correlation [1] between IQ/SAT scores and numbers of patents/PhD/science publications even among people in the top 1 percentile of the SAT-M - i.e. roughly IQ 135 or more. (This is even more significant given how imprecise the SAT is as a measurement tool at the edges of the bell curve.)
Some studies showed that beyond 130 the benefits of a high IQ plateaued and that's assuming you put much faith in IQ scores which I don't since I know roughly where I fall on the spectrum and I know my score and my score says I'm considerably smarter than I actually am :).
