I like creative when I just play singleplayer and want to tryout things, like that quarry.
My computer had some trouble with Minecraft though, the settings were on fancy but I ran out of memory really fast. I can run Project CARS on very high quality without any trouble.. Weird.. Looks like Minecraft is a little heavier than it may look.
Maybe upgrading to 64bit will help, but I only have a 32bit copy Pff. First world problems
