Depends on the trading frequency of your strategy.

If you managed to create an EA that traded many many many many times a day, you could make a fortune with a profit factor just above one.

If your EA does not trade very often, you need a higher profit factor to overcome inflation and opportunity cost of sitting unused margin.
