Is the 105 a big difference over the Tiagra?
You won't notice any difference IMHO. The primary difference is weight. That said I personally consider groupsets in two categories - bear in mind I am only referring to Shimano.
2300 to Tiagra, and 105 to Dura-Ace. So by my way of thinking, 105 is the first of the top end groupsets. This is just my opinion mind. I've never used anything below 105 for a ride of any length, and IME the man in the street will not differentiate between 105, Ultegra and DA.
I have full DA on my CAAD10. In fact I preferred the DA that was on my 2006 Trek Madone 5.5, that was noticeably better, but hey ho who am I to stand int he way of development!
IMHO if you opt for anything less than 105 on bikes of this caliber you'll only be hankering after upgrades before you know it

FWIW, if you have the option, I wouldn't personally consider Campagnolo on a road bike of this genre for all the tea in China. I find it generally too agricultural. Then again if you have the chance, try it, you might love it, just food for thought
