In general (regardless of your software) do you do your editing on one computer and then copy the final completed files over to a show computer? Or do you use one for both?

Currently I use my main desktop to do all the editing and running the show. However, this computer is also the one I use to play games, surf the web, run my very small etsy shop, etc.

I am considering buying a lower end i3 or i5 laptop to have exclusively run my show and have it set up in the garage. Just curious about everyone else's setups.

Would the movement of files cause issues? Obviously I would move the files from one computer to another and then properly test them before putting the show in a live mode.
