so would 2070 be a dud?
All boost lock does is lock the core to the max VF curve voltage. This will vary depending on whether you have the voltage set to 100% and the shape of the VF curve at the time (sometimes by default it will flatten out before 1100mv depending on the state of the card).
It has exactly nothing to do with the quality of your card. Only how far you can push clocks will determine that.
