"Considering anything above 50 DPS is already OP, I don't know what to select..."
Its really not... against powerful bosses, even 1000+ dps is weak. If youre still havin a hard time, look at it from a pvp perspective: enchanted diamond gear massively reduces damage, even in vanilla, and powerful boss monsters have similar amounts of resistance.
You wouldn't go solo against a high level boss, you usually have a team. 1000+ DPS is probably equivalent to that much damage or more, depending on the attack speed. I mean, in the past age, those types of weapons could've existed, but I highly doubt there's many weapons like that around anymore.
The only difference between the Past Age and now is that the resources available were different. As this question is theoretical, there no real limit. This question is purely for fun, a mere trivia question. Let nothing limit you: you could have the highest enchants, the most legendary materials, best craftsman, and the sharpest sharpshooter
