I don't know anything about the pSeries, but have a look in the 
archives, there was recently a rather long thread about Xeon vs. 
Opteron. The Opteron was the clear winner.

Personally I think that you can't be wrong with the 4-way Opteron. It 
scales very well and if you don't need the fault tolerance of the 
pSeries platform, then you should be able to save one or two bucks with 
opteron way.

Btw: If you want to save a few more bucks, then drop the 15k and take 
10k drives. They are of almost same speed.
