Pi Zero overclock?

hi

got a pi3 so far love it, my original intention was to turn it into a dedicated amiga box but now I kind of want to play around and use it as a linux box since pretty much replaced my android settop box.

for as little as $10 I figure why not get a PiZero too? an extra box I can play around for that little cost maybe fun!

TLDR

does the zeros default 1ghz overclock need additional overclocking to run Amibian or is 1ghz fine?

Thanks
