Thanks Joe, I saw both SSE4.2 and AES-NI being supported there even if it was a datasheet for the v1 or v2 (was from 2012).
This leaves AVX 2.0 which is not mentioned in the datasheet as it is for the older E5's. Does the E5 v3 series have that onboard yet?
2+ sources claims that the E5 v3 has AVX 2.0,
