That would be interesting, but I really don't think anyone will do dual GPU due to costs alone.
I will update the cpu/gpu tables later today with the data you guys said would be better compared. I'll also add info on the actual gpu in the apu rumored for comparison's sake.
However, in the end I don't think it matters. I really think that all three will be close enough that it will simply come down to first party and unique features. In that fight, only Nintendo has the clear advantage. So long as other rumors on their OS and networking capability prove to be true.
