Trouble with solving huge non-linear matrix problems is that they don't 
parallelise at all well. You could well be better off with whichever of 
the current CPU crop has the fastest single threaded performance.

Provided that it is only for scratch working it is still worth at least 
considering using the dangerous for risk of data loss RAID0 in a matched 
pair configuration to nearly double effective disk bandwidth. There is 
much less advantage doing this trick now than their used to be.

Obviously data is toast if anything goes wrong so don't store important 
results on it long term. I no longer bother but it might help you.
