I might be able to shed some light.

The r5k processor is not always faster than an r4.4k processor.

It is a rare person who would be best served by an r5k o2 versus the
desktop SGIs (meaning r10k o2, octane, or decent versions of the I^2).

If you don't plan to do video on your O2, than an r10k o2 would be
better.  And if you don't plan on doing volumetric rendering (which
usually means medical work, or other scientific visualization), than a
Hi Impact with Tram, Max Impact, SI w/ TRAM, MXI would be faster
graphics wise.  And actually any Octane would be better at video
handling for the most part if it weren't for the cost of the bloody
video IO board.
