Benchmarks When running tests, installing operating systems, and compiling software for my Ultra 5, I came to the stunning realization that hey, this system is 64-bit, and all of the operating systems I installed on this Ultra 5 (can) run in 64-bit mode.

Ummm, I disagree. Read on.

Note "that make heavy use of floating point variables/registers directly"

Maybe not the best wording; maybe I should've said
"that often directly use floating point registers"
or even
"that often load/store floating point registers"

Your examples are brilliant, as they show exactly what I wanted to express.
