Wow, that's quite impressive, I was on newegg earlier today and noticed a bunch of 600 series Intel processors and was wondering where they hell they all came from.
AMD still has a few clear advantages over the Intel 64 bit processors, they still seem to be using the hot prescott cores so overclocking could be a problem, and AMD still has the socket 939 dual core futureproofing, whereas the Intel processors on Socket T do not.
The 2MB L2 cache looks quite appealing though, perhaps I will have to reconsider my next processor choice...
