Yeah, the only mobos around for them at the moment are ~£250, and the ram MUST be DDR3, which is otherwise near-unused and rather expensive. (you know all this already, I know, but for spectators to the thread)
Where did you see the gaming performance?
I can see what youre saying on the price, it is high, but from what benches I've seen theres no reason whatsoever to go with anything but the 920, which is oh so very slightly slower than the 940 at about half the price, and still rather a lot faster than QX's at 3 times the price. I *think* that even the 920 is faster than any C2D (not quite sure, but I've only seen any i7 beaten in benches by dual QX somethings, I think it was QX9770s, and even then its not all the time. The 920 is looking like AWESOME value for money, on its own (without the mobo and ram!))
