Hallo Zixx,
first: Your post appears to me in a tiny font not readable. That's strange.
To the puzzle: I'm pretty sure this Sudoku is strictly speaking not solvable because it is incorrect in its hints. The three gold cells in box 5 do not work. I might ignore this and start with what I see in box 9; maybe I try this.
And to your general question: I think besides putting in the up to three candidates for the gold cells there is nothing special you might do besides of course in this special case looking at the equal sum line.
