general advice

Hi everyone,new to this forum and new to raspberry+Volumio+external DAC extension,having no IT background(just use it for leisure as most of us here)please excuse the “stupid” questions.Before making the final leap,could anyone give advice on the best choice to use volumio,knowing the latest iteration has 64 bit processing,whereas the former has only 32 bit processing,in other words,is it of any use to have 64 bit processing to work with volumio and hifiberry dac pro for example?
