Building a PC, and planning on using an Xeon processor. Originally was going to use a 1231, but see that the 1220 is over 20% less. Differences seem to be operating frequency and Hyper-Threading. Should I pay the extra money, and if so, why?
Intel Xeon E3-1220 V3 3.1GHz Quad-Core Processor
Intel Xeon E3-1231 V3 3.4GHz Quad-Core Processor
