Have you selected MPE settings in the premier project?
Besides that, be aware that rendering is mostly a CPU-intensive task, your GPU will not work as hard as your CPU cores will. Also I reckon having more ram will help with the rendering speed.

How do you know that is why the render is taking 5 hours because of the GPU usage and not simply because that is how long it takes with your system? Did you check other sources to see how fast a video like the one you are doing should take on your CPU and GPU?
