If gold got to $600 it's because the selling pressure by parties unknown (try a few Central Banks) have an agenda. So equally likely pressure would come off the POG and....zip....your sitting on a holding rising fantastically in value.
No need to sell the house etc. Just pray that gold gets to that price.
Anyway the global economy is in such a state there will most probably be a risk off change is sentiment and a run for the hills scare at some stage.
