Barring something being broken, the 105 components on your current bike should be able to be adjusted to work quite smoothly. So in my opinion you shouldn't have to upgrade just to get things working nice.
Now if you want to upgrade, then that's a different story (and there's nothing wrong with that.) I'd go the Dura-Ace route. Cheaper, and a better deal. Probably so close to the newer Ultegra model that it would be hard to pinpoint the differences in performance. And then your bike would say Dura-Ace on it for that "wow" factor.
