Not if you know where to spend your skill points.
Minimum Intelligence 3 plus implant rush allow you to significantly boost up your special but not much impact on your skills.
This argument doesn't make any sense. Skill points are skill points. They make your character better at something. Just because you can play effectively without more doesn't mean more of them are useless. The question is if 60 skill points by level 30 for every 2 points of intelligence is more or less effective than adding 2 points to some other SPECIAL stat, which it clearly isn't.
Strength: carrying stuff is useless with companions, and 30 skill points is obviously better than 1 base SPECIAL point
Perception: Pretty useless in general. My Sniper build is just as effective with his base of 3 and with his effective of 7.
Endurance: Only a minority of players play hardcoe, and even those of us that do should have figured out food and water aren't really a problem. More hit points is hardly better than raising a different skill by 60 points.
Charisma: once again, your companions don't become so much more effective that it's better than giving yourself the extra skill points. And you get way more extra skill points for speech/barter with two intelligence than you do with two charisma
Agility: Again, running faster has little mechanical benefit and 60 points for SNEAK is obviously a better effect
Luck: Since no skill can really raise your crit chance, and two luck is arguably more effective at getting you caps than 60 Barter, this is really the only stat that stands a chance against intelligence. But since it's a specialized skill, I think we can claim intelligence is still the best skill for the vast majority of builds.
