I'll wright a more formal argument when I make a conclusion. But one thing that I don't see brought up is that you can unlock the 6128 Magny-Cours to 12 cores. Not all ways and not 100% but It is a factor, Its is a gamble you could get 1 extra core or 2 or 3 or 4. I also think the team needs to find ways to keep the heat down. If you can control your heat you can run 4 v cards.
