Css transition all Vs specific transition

Question

I used to add a class with .easeMe name to my css files and then every time I want to fade an element just add this class to it .

.easeMe {
    transition:all .7s ease-in-out;
   -webkit-transition:all .7s ease-in-out;
   -moz-transition:all .7s ease-in-out
}

But today I was thinking about making better performance , and I thought if we add specific transition for properties it maybe give a better performance like :

.easeBorders {
    transition:border .7s ease-in-out;
   -webkit-transition:border .7s ease-in-out;
   -moz-transition:border .7s ease-in-out
}

Or about width,opacity ... Is it a correct idea ?
