Cuando tu vas, yo he vuelto

[ROBINDESBOIS]

Meaning I´m far clever than you. DO you have a similar expression in English?

[poli]

I'll beat you to it.

[ROBINDESBOIS]

Can you say when you go I´m back?

[pjt33]

I'll be there and back before you're off the starting blocks? But that sounds too athletic to me; I don't think anyone would understand it as intellectual braggery without some strong context.

[bobjenkins]

A mí me gusta esto dicho:D:D

I´ll beat you to it - es una buena traducción

Anything you can do I can do better - mi añadido

[hermit]

all good - perhaps "i'm way ahead of you.", as well.
