I'm a vim user, not an Emacs user (though I have dabbled with emacs before). If you still use vim on the console, you can do a lot better.

There's a reason why vim has support for multiple buffers. That you can keep multiple files open simultaneously. Read about vim remoting, and you can use a single gvim instance (which offers better performance and font rendering), and edit all files in just that.

Even in emacs, buffers are everything. Nobody opens a new instance of emacs for each file.
