Using get_tmplate_part() function in WordPress

I am making a wordpress theme, in which I have different skins and templates, Is it a good idea to use get_template_part() function to load different chunks/templates instead of having one single file. I find it useful however my only concern is, will this function put load on server or effect the performance in any way ? I am using it like below:

  /* Post Tags Template */
  get_template_part( 'templates/post_tags' );

  /* Post Meta Template */
  get_template_part( 'templates/post_meta' );
