I made a wizard with minimum Intelligence, and I do not plan to even get the headband. There are so many great wizard spells that don't require high Int to work. All I need is Jump, Expeditious Retreat, Feather Fall, Fog Cloud, Sleep, Magic Missile, False Life, Grease, Mage Armor, Invisibility, Mirror Image, Misty Step, eventually Haste, etc.
Not sure it will really get you far in a fight. Magic Missile isn't all that good in the long run. Unless you are building a melee fighter.
