Joe, what i would do before I invested in a new radiator is flush your rad out. I flushed mine out with 3 gallons of vinegar by going for a 30 mile drive, Came home and drained it and used a 2 /3 vinegar to water, went for a drive and drained it and then did a 1/3 mixture and drained it. I then ran water through the rad, filled it with water and went for a drive. I repeated this three times and my water was finally clean after the last drain.
I bought a hand held heat sensor from Napa and shoot my temp regularly, i80 degrees is not out of line IMHO
