1. AFAIK you can't have a single CPU Onyx2IR. A single node card contains
two R10Ks.
2. Origins don't have GEs or RMs. Graphics capability is limited to what can
be done under X.
3. Multiprocessing will only buy improved performance if the task can be
appropriately split up to take advantage of the additional CPUs. More CPUs
doesn't neccesarily imply better performance.
Given the graphics requirement, the fact that the major difference between
Origin and Onyx is graphics and stirring in 15 years of flight simulator
experience, my vote would be for the 8 CPU Onyx2IR.
Of course you could Craylink an Origin and an Onyx and really go to town...
