at 5TB data, i'd vote that the application is disk I/O bound, and the
difference in CPU speed at the level of dual opteron vs. dual-core
opteron is not gonna be noticed.

to maximize disk, try getting a dedicated high-end disk system like
nstor or netapp file servers hooked up to fiber channel, then use a
good high-end fiber channel controller like one from LSI.

and go with FreeBSD amd64 port.  It is *way* fast, especially the
FreeBSD 6.0 disk system.
