CPU = Speed
GPU = Visual
You can have the best CPU in the world but only run the game at 100%, windowed and at native resolution.
Alternatively; you can have the best GPU in the world and see the game in the highest quality possible, but not be able to play it as it runs at 50%*
Whilst 4.7GHz sounds impressive, AMD cannot compete with Intel when it comes to high-end CPU's.
Using an outdated version that suits your processor is fine for now; if the games run at 100% constant then yes - upgrading your graphics card is the best step to improving the visuals.
However: Dolphin is a constant updating process - everyday there are new builds, new features, bug fixes etc... At one stage you will want to upgrade to the latest version whether it's a stable build or development build purely due to the compatibility.
It may be worth thinking about investing in a new CPU in the future - AMD can't cut it at present. For more information google for the dolphin benchmarking utility. You can see how well different CPU's perform within Dolphin which will give you an idea at how fast/well they will perform
