It's probably just that you have a bad dump of the game. See if the .iso's MD5 hash matches the one on redump.org or gametdb (or, for Wii games, right-click > Properties > Filesystem tab, right-click the game partition and Verify it); if it doesn't match (or verifying says your copy's bad), you'll have to redump the game from the original disc.
Also, 4.0 does have a few known bugs (e.g. one specifically related to single-core mode) which are fixed in 4.0.2. Go try it: https://dolphin-emu.org/download/
And, as reading other threads on the forum will make you painfully aware of, any framerate drops you're getting are more the fault of your CPU, not your perfectly-adequate GPU. Dolphin is a highly CPU-bound application – CPU speed determines game speed, while the GPU only really determines how high you can set the resolution/AA without it slowing down. AMD's CPUs in particular are kinda crappy for Dolphin – some Haswell chips at stock clockspeeds (e.g. i3-4130 at 3.4 GHz) are faster for Dolphin than an FX-8350 at 5 GHz (!).
