For high internal resolutions and high levels of anti-aliasing, yes, you need a good GPU. Most cards, however, will have no problems with high levels of anisotropic filtering when it comes to Dolphin. Afaik, it's not nearly as expensive in terms of computing resources as the other two. At least, even the measly GMAX3100 in my laptop suffers no performance decrease if AF is set to 16x instead of 1x.
