E5 2670 is LGA 2011 while E5 2670 v3 is LGA 2011-v3.

The LGA 2011 socket is used by Sandy Bridge-E/EP and Ivy Bridge-E/EP processors with the corresponding X79 (E – enthusiast class) and C600-series (EP – Xeon class) chipsets. LGA 2011-1, an updated generation of the socket and the successor of LGA 1567, is used for Ivy Bridge-EX (Xeon E7 v2) and Haswell-EX (Xeon E7 v3) CPUs, which were released in February 2014 and May 2015, respectively. LGA 2011-v3 (also referred to as LGA 2011-3) is another updated generation of the socket, used for Haswell-E and Haswell-EP CPUs, which were released in August and September 2014, respectively. Updated socket generations are physically similar to LGA 2011, but different electrical signals and ILM keying prevent backward compatibility with older CPUs.

Look for a Sandy Bridge-E compatible board like the X79 platform or look for X99 platform boards or conversely Haswell-E, Haswell-EP or Broadwell-E chips.
