<p>Honestly, forget retaking it if you have 790 on the other sections, unless you are interested in Caltech like collegealum said. That school really likes to see the highest scores in everything, although there are of course exceptions [given it’s such a small school, I think anything that might disqualify you should be something you might want to eliminate].</p>
<p>For all other schools, just aim for a very high Math II score. An 800 or close should be no problem if you prep.</p>
