Your CPU is not half bad but your GPU is very weak.
A laptop version of the 8400 GS is even weaker than the desktop version I would guess.
You can try upgrading your Dolphin version to get better performance. There are new versions in this section of the forum: http://forums.dolphin-emu.org/forum-6.html
Dolphin is up to version 4580 and further already
Also you may want to share your settings, maybe someone can help you to optimize Dolphin performance that way.
