Well yeah, that is the exactly the situation I described as when IO throughput is important... I would say that this situation does not represent the majority of users. It only applies to people...

The power consumption is around 130W per machine, so it's pretty much right at 2kW total. I have not run a generic benchmark, but it is about 15% faster per core for our simulations (~50 million...

We already had a four node cluster with gig-e, and were seeing diminshing returns on the speedup. It was never a thought to go all the way up to 15 nodes without a faster interconnect.

We currently have a four node cluster built with i7 980X chips and cheap motherboards, RAM and power supplies. This has run fine for us for about six months, and now I am planning on scaling it up...
