look at this

it is interesting to see how much will AMD price each of the processor, i dont see any reason to get these processor if it is at least 50% pricier than intel's core 2 duo, unless it did really perform as what they claim now.

the 4x4 platform, where u need to buy the processor in pairs, it is available now but it is very expensive. simply put, combine 2 processor on one mobo. if u got two quad core, u get 8 core total.
