Itainiums are good only in milti-CPU setups, and they are not based on x86/x86_64 instruction sets. They have thier own instruction set, something like AI_64 or summint like that. Anyway, there completely useless for home use and as I said, mainly only for huge multi-CPU arrays for the most demanding servers running specialised software - such as huge databases or for being the platform for virtual servers.
They do have support for x86 applications but this in emulated, and not natively supported, so run terribly slow compared to an equivelently clocked x64 or x86 CPU. For example, when the P3's were out at about 1.2GHz, the Itainiums were running about 1.2GHz as well, but when running x86 software, performed like P2's 266MHz. Not good.
There for specialised use only. Not for us, fortunately when you look at the price!
