I will be getting 2 servers today and bringing them home to start mining BSTY.  Below are the specs on the processors in the box.  These are the Google Search boxes that Dell made for them.  

One is a Dell PowerEdge 2950 and the other is PowerEdge R710.  They both have 2 CPUs each.  Below are the tech specs on the CPU's.
