Thanks to everyone for all the feedback. This is exactly what I was looking for. We all get excited about the prospect of a new bike but if I'm not going to get much of a return on investment then it wouldn't make any sense. With that said, I may still make an change/upgrade but just to a lesser extent. My current ride is made to be really upright and I'm ready to get lower. It's also heavier than what I'd really like. I'll probably look at one of the bikes I mentioned in my original post but move down to a 105 instead of Ultegra and save some. I feel I'll be happier and more confident on something a little more built for speed and comfort as opposed to almost mainly comfort.
