It all depends on your internet connection speed. Mine took about an hour to download, while my friend's took four hours. Right before Gmod starts downloading, it will tell you how long it will take.
gmod 9, yes gmod 10-no
go to steam.com here are some links related to Gmod to help you: Steam: http://store.steampowered.com/ Download stuff to Gmod here: http://www.garrysmod.org/downloads/ About Gmod: http://www.garrysmod.com/about/ Gmod fourums: http://www.facepunchstudios.com/
When you are at the steam store you can select the game and it will tell you its size.

umm ok this doesnt make this much since, if your asking if gmod damages your computer, it depends on which gmod you have (if you got it free its gmod 9, if you got it for $10-13 its gmod 10/11). in gmod 9 there were LUA viruses, in gmod 10 there are fake addon viruses so you should just scan for viruses when you download addons (www.garrysmod.org). if you play online there are some players who find it enjoying to spam props and nukes until you crash. also if your computer is lower-end then some of the maps and addons can crash it. but OVERALL no, garrys mod does not damage your computer, some addons and players do. just be careful which addons you download. if your just playing gmod to build contraptions, probably no dammage there. OK now if your asking about some sort of computer in gmod (PCmod?) that damages players or something like that try www.facepunch.com/index.php
from 10 to 15 minutes

To download Internet Explorer 10, one must visit the Microsoft website. The download links are on their website and shouldn't take long to download. There are many languages available.
gmod 10 is the last one, I don't think they'll release any more.
