It's fairly deceiving when certain SPEC2000 components will *slow down* from 64-bit mode.

True enough. Complete SPEC scores for Intel and competing processors would be useful. I wonder if x32 mode solves this problem with SPEC? X32 mode is supposed to give the best of both worlds - all the x64 benefits (except address space increase) without the overhead of 64 bit pointers.
