I thought it was pretty clear from my post that I was comparing single core to single core, and multi core to multi core... and the only single core archi from Intel in recent years has been the P4s. I guess maybe xeons could be considered a different CPU, but they are also clobbered by their opteron equivalents... and I did say Intel were killing them in the multicore deptt didnt I ?

As for 4 cores, Of course 4 cores arent as big a jump as 2 cores, that's just how SMP works. But 4 cores with 2 pairs of cores sharing a cache is still a lot better then 4 individual CPUs, which is all that was possible before they came up with the core 2 quadro. And who knows they may make a fully shared cache version in the near future, they are just getting started with multi cores after all...So i for one am quite excited by it, but i admit that its partly because I use other apps besides Poser that would indeed make good use of them.
