All stats, except intellect, have some direct effect on combat (charisma - through your companions).
All stats, except intellect, have some good perks, associated with them, requiring them to be above 5.
So the SP rate is the only thing requiring high INT, and it is abysmal. (15 SP per point of int throughout entire game.)
There really is no good reason to raise INT above 5. Even better, to lower it to 4, IMO...
INT may still affect dialogue a whole lot. I highly doubt they'd make it that useless.
