Yes I do think that's realistic, lowest range of each model is usually the best-selling by far, why do you think AMD are so careful with the lowest X2 price they set as when they priced Opteron 165 below it that sold out as that was the cheapest de-facto X2 ;-). I'm sorry you can't take credit for me researching AMD data as that came up in a discussion on Aces, data which I remembered half of at the time but not where it was ;-)
