Strength isn't really needed at all, but you can invest in it for the hell of it Dexterity is pretty useful for ranged attacks and AC, but not entirely necessary Constitution is always nice, but you already have the eidolon to give a massive bonus to health Intelligence only helps with skills ranks, and the summoner doesn't really get any skills Wisdom isn't all that useful except for will saves, which summoners get a good bonus to Charisma is used for casting, but summoners aren't full casters so you're not dependent on it
