Hmm, what is "ridiculous about Opteron pricing?
In HPC work one generally needs a XEON clocked about 20% to 25% faster
than an Opteron for equivalent performance.
Mainly due to the limitations of memory bandwidth of the XEONs.
Current CPU pricing comparison:

Or Myrinet. Bandwidth is usually unimportant, but latency usually is.
So called "memfree" IB cards are rarely any kind of bargain for this use.
