Guys aren't necessarily intimidated by beautiful women who are extremely accomplished. In fact, this can be a turn on to many. However, just as women typically don't like a guy who talks about himself constantly and brags and blathers on about all of the great things he does in this world, men feel the same way too.
From your question it sounds an awful lot like you may be someone who needs to chill out on your perceived glories. Most people would rather hang out with a solid D student than someone who flat out tells you they have a 3.7 GPA. Geez! And all of this business about artistic interest and social circles and a competitive internship--honestly who gives a crap?
My advice, chill out. Be confident in who you are but don't be a pretentious braggart. Next to cheapness this may be one of the top turn offs, not just in dating but in every other social aspect.
