There are shader operations the Wii can do that the GC cannot do. While it's not a huge increase in the shader library, new ones do exist. Thera are also more pipes in the TEV. Also having a faster CPU, GPU, RAM (and more) and buses allows for more shader ops at any given moment over the GC.
A "refurbished" GC would mean no changes at all. It's actually a misnomer completely. To be refurbished, a unit would need to be broken and merely restored to original spec and operation.
The mere fact that Wii has new hardware voids his statement completely.
I cannot believe it is 2010 and we still have people claiming Wii to be no more powerful than the GC. I implore you all who share that belief to do some actual research instead of hanging on to the ficticious ramblimgs of fanboys.
