it's not clear what 'these' refers to.
48 core AMD multicore machine: $8000 on ebay i saw one for. Of course
not much of a RAM and not fastest chip.
Let's say fully configured about double that price.
GPU monster box, which is basically a few videocards inside such a

But a 8 socket @ 10 core nehalem-ex, in basic configuration will be
