While I'll agree that the EM64T (Nocona) Xeon processors are not as
large an improvement as the Opterons are, they _do_ have better busses
and caches than previous Xeons, and the supporting chipsets are
significantly improved as well.
I've never seen a Xeon DP/MP machine (previous generation) that had an
800MHz FSB, supported dual-channel DDR2 RAM, or had a 3+ GHz on-chip cache.
