The Wii GPU isn't remotely similar to any PC GPU released since the DX7 chips of the late 90s. It uses register combiners instead of the programmable pixel shaders used in DX8 and up. Like you said, PS2 emulation is CPU bound. With Wii/GC, CPU emulation isn't as difficult, as they use single core, single threaded PowerPC 750 cores.

D3D Pixel shaders are more powerful than register combiners so I don't know what your trying to get at. Even if it ain't exactly like a PC GPU other PC GPUs that had D3D pixel shaders supported superceded the ati flippers register combiners. 

Register combiners can be emulated by programmable shaders, but in terms of developing for it, the hardware is very different, you have to use totally different techniques. Wii's GPU is not similar to any PC GPU from DX8 onwards.
