If you had been in later position I would almost definitely call to play a pot hu, in position against a weak player (I highly doubt he's a strong player if he's 3betting this huge).
Right now I think it's close. I guess you could call to play in position with a decent hand anyway, but folding is definitely not bad. You're still very deep so there's going to be much better spots later 
Hey BigBenMee!
I fold against the incredible big 3bet! You are very often dominated imo!
Against a normal 3bet you can easily call... but in this case I fold!
