I took a real IQ test like a million billion years ago to gain entrance into a "gifted" educational program in middle school, and back then I scored a 130 IQ, which is 30 points above the average.
Intelligence can be beneficial to nurture creativity as a PUA. I guess it would make it easier to make your own routines and stuff, but there is a different kind of intelligence that is 100 times more important than the type of intelligence we're talking about. And that's called Emotional Intelligence.
Those guys in class that don't pay attention to the teacher, but spend their time flirting with girls are developing Emotional Intelligence. Those guys who spend their nights out at the club picking up chicks while sleeping through their morning classes are developing their Emotional Intelligence. I wouldn't recommend sacrificing your grades like that, since I had pretty shitty marks this past semester because I was that guy going to clubs and sleeping though classes lol.
Intelligent men usually forget about developing their Emotional Intelligence, though, and that's a pretty dumb mistake.
Now, what exactly is Emotional Intelligence? I believe it's the NUMBER 2 FACTOR that determines whether or not a PUA is going to get laid or not. The number 1 factor, I believe, is leading frame. Emotional Intelligence is that thing that gives you a FEELING of "I should do this if I want this" in response to specific cues around you. This feeling cannot be rationally thought out completely. It also gives you the FEELING of "this means this on an emotional level." Emotional Intelligence lets you FEEL the truth, whereas regular intelligence lets you KNOW the truth.
If you're a "smart" guy, I bet you might have some catching up to do in the Emotional Intelligence department. There's only one way to develop it: In-field experience. You can't develop this type of intelligence by reading about it in an ebook. That's one of the gajillion zillion reasons in-field experience is so important.
