One of the better upgrades I did was get a better quality set of riding jerseys, bibs, and winter weather riding gear.
I have to agree that having the proper riding gear was a quality investment.

Actually, those might do more than the groupset. Unless your mechanic sucks or your gearing is inappropriate upgrading groups won't really do much.
Pro fit was also a quality investment, very good results in my power output and comfort on the bike.
