So your stat is good...your system comes to pressure but you are still overheating? The radiator itself might be bad. You can try a flush and see if overheating subsides.
You could also look and see if the coolant is flowing and the stat is opening up by looking into the radiator when the car is cold and starting it and running it to temperature.
Did you pressure check the cap? Sometimes they break and you don't get adequate system pressure with the cap in place.
