they had a different design goal (mhz mhz mhz).. so your argument that
they're the same is disproved just by your statement here already.

you can if you pick your system with a tiny bit of care. Basically all
gige nics are 64 bit capable (maybe a $4 nameless one excepted), and
AHCI sata is too. All scsi that was made in the last decade is as well.
Nobody makes high speed pci cards without it basically, and the on board
stuff is normally ok as well.
