That CPU is not looking good, AMD chips are second compared to 4th gen Intels in single threaded performance. Dolphin likes i5xxxx or i7xxxx series, especially the ones that are capable of overclocking. What version of Dolphin are you using? You may want to try older builds but keep in mind that you will not get support for these builds in the forums.
