Is my computer good enough?

Dolphin doesn't need much from the GPU, but your Intel HD 3000 GPU is hurting you.

Your CPU should be fine, assuming you have adequate cooling and are not being thermally throttled.

That said, you can work around your very weak GPU by setting the Internal Resolution in the Graphics > Enhancement settings to 1x or 1.5x. Any higher will choke your GPU.
