4 Old Gods at full power > 1 Titan (and thus Sargeras), easily. Sargeras may be empowered, but there's no way he is 4 times a Titan in terms of power.
But the Old Gods aren't at full power, so it's not as easy to predict as it seems. Secondly, we don't know if the Old Gods would work together. It has been shown that they can, if they really need to, though.
So to go with the hypothetical situation: 4 fully powered Old Gods vs Sargeras = Sargeras is dead meat.
