Currently have a 2006 Specialized Roubaix triple with aluminum frame and carbon fork and seat stays.

I am considering trading the 2006 in on a new 2010 Roubaix with full carbon frame, compact 105
drivetrain and components. Do you think I'll notice a better ride, and in short, is it worth the upgrade?

I don't race, but ride 2,500-3,500 miles/year in the Fort Worth area.
