It all depends on how much you want to play it. It's possible for people with Aspergers to function relatively normally, with the right type of training.
I seem to be doing reasonably well, for example. Most of the people who don't know about Aspergers wouldn't pick out anything wrong with me.
(my recent diagnosis was quite a shock, I must admit. explains a hell of a lot about my childhood.)
So, honestly, pick what you need for cool role playing, and pick the limit based on that.
Always go with what's cool, not so much on what's realistic.
