If you wish to max out your character's SPECIAL, follow my simple guide below: On the Xbox 360 version, so I can guarantee there were no console commands involved. I've heard people say that it's impossible even.
Unfortunately, Fallout: New Vegas made maxing out your SPECIAL quite a bit more difficult. This was easy enough in Fallout 3 - you practically tripped over skill books everywhere you went and with the Almost Perfect perk, it was easy to raise your SPECIAL to 9 across the board, then collect all of the Bobbleheads in order to bring them all up to 10. I love to collect every item, finish every quest and max out all of my characters' stats and abilities.
