[ubuntu] CPU Architecture

view story

http://ubuntuforums.org – Hello Gurus! I've been testing Ubuntu (and environments) for a while now and I'm looking to do the cleanest install possible. My Question in fact is, what is my CPU Architecture based on Intel(R) Core(TM) i5-3570k CPU. AMD64 or i386, other? If I'm not mistaken it is a 64-bits system. Is downloading Ubuntu-Desktop-64bits good enough? Thanks a Lot! :) (Hardware)
