Yeah, that's something to bear in mind; SGI workstations have a plethora of CPU options, so they were available in many configuration from cheap budget machines to high end number crunchers.

The Fastest O2's are O2+'s, but they're really only different in the case colour (purple vs. blue) and the logo (Cube vs. that weird-ass script logo). The R5K O2's can sport anything from R5000PC180 to R7000SC350, the R10K model can be equipped with R10000SC150 through R120000SC400. Unlike Indigo2, however, a different class CPU on an O2 means a different motherboard.
