I hope you chose Intelligence 9, because it is the same as 10. 9 grants 14.5 which rounds up to 15 SP, same as Intelligence 10. Otherwise you wasted a S.P.E.C.I.A.L. Personally I went for I8, and got Intense Training to 9.

Not true. New Vegas has changed how that works.
Odd numbered skill spoints don't round up, they get carried over to the next level to make an even number.
Example; 9 intelligence grants 14.5 skill points, but you only get the 14 on the odd numbered levels. On the next level you get the last 0.5 carried over so you gain 15.
In total you lose 1 skill point over 2 levels if you go with 9 (or any odd numbered) intelligence,
I personally ran to the implant lady as soon as i left the Doc's house, only picked up the Caravan deck and the first snowglobe. That was enough to give me the money for the intelligence implant, so i got that on level 1.
