Thats no better than the 2660 V1's in my servers, I am not sure the lower power use of a V2 is worth paying so much more for them to mine Monero.
From my Monero Open Compute build :
Dedicated Crypto Mining Open Compute server build.
"No cores turned off.
One server plugged in and both nodes powered off: 15w
One node powered on, Ubuntu 17.04 server booted up and idling : 56.5w
One node after 10 minutes mining Monero with 20 threads : 208w @ 868 H/s
Two nodes powered on, Ubuntu 17.04 server booted up and idling : 117w
Two nodes after 10 minutes mining Monero with 40 threads : 401w @ 1736 H/s
So two Open Compute servers running eight E5-2660 V1 cpu's are mining Monero at 3472 H/s using 802 watts."
Nice, thanks for the results. Had an employee set up a dual E5-2660v2 -- running @ 920h/s. Dual E5-2660v1 @790/s. I'm assuming it's similar power use (haven't checked the v2 yet), so the extra performance is worth it to me. Using the docker image on the first post of the thread. Will be able to get power use figures in a few days.
Klee -- 200w per Dual E5-2660v1 -- sounds pretty good. Leaves decent room to improve from my first try.

any idea of the perforrmance vs power savings of E5-2650Lv2 vs E5-2660v2?
same core count and cache. similar cost to buy.
2650Lv2 has lower clock speeds, especially max turbo clocks, but 70w tdp vs 95w tdp of the E5-2660v2.
Tempted to pick up a pair of the 2650Lv2's to compare, if nobody has tried it yet I can post back the results.
In the same tests, Dual E5-2660v1 did 790/s or thereabouts, and 920/s for Dual E5-2660v2. So certainly leaning towards v2's in general.

As an update, I was able to get a supermicro 1U down from 240w to 210w mining with dual E5-2660v1. 17w of the reduction came from disabling 2 of the 8 cores. The rest of the reduction came from removing 6 of 8 sticks of ram and removing 1 of 5 fans.
Some one posted the hashrate for E5-2660v2.
No one reported hashrate for E5-2650L v2.
I need more E5-2650 or E5-2660 , I think I'll wait for v2 price to drop down to $35 difference. Then make the buy.
My Intel 4nodes 2u server results , about 195 watt each node
Intel S2600JF 4 nodes with dual E5-2660 , L3 cache 20MB , 2 x 10 Threads , BIOS active 5 cores
each node is 845-850 H/s , total 845 x 4 = 3360 H/s , 760w - 772w , 4.42 H/s per watt
Intel S2600JF 4 nodes with dual E5-2650 , L3 cache 20MB , 2 x 10 Threads , BIOS active 5 cores
each node is 760-765 H/s , total 760 x 4 = 3040 H/s , 640w - 664w , 4.67 H/s per watt
each node consumes about 160w

Very interesting that the dual E5-2650 gives better hash per watt than the dual E5-2660 despite lower performance per cpu and identical TDP.
A seller had E5-2650L v2 for 99USD, other sellers are around 130USD, offered 65@ and qty 4. He accepted had been on ebay for a while and no sales,, someone else just picked up 32 in one go..They will go into SM 1U twin I have for mining.
With 10 cores / 25MB L3 cache / 1700 MHz / 70W, they may not quite offer the higher hash rate of 2660 v2 and 2650 V2, but I liked the price, will see what performance is in a few weeks when I receive them in the land down under.

Just made offer for 4 at 60 each will see if he accepts..

Looked at the options 2650v1 ($40)/ 2650v2 ($110) / 2650Lv2 ($65) looking at what best offer prices could be.. and the following
CPU / Mhz / Cores / Cache / Watts
2650V2 / 2600 / 8 / 20 / 95
2650V1 / 2000 / 8 / 20 / 95
2650LV2 / 1700 / 10 / 25 / 70
c.f. with 2650LV2
the V1 had 20% less cores and cost plus33% more power
the V2 had 20% less cores, plus 33% power increase plus double the price plus 50% more frequency. so as I already had 2660V2 was keen to keep capital costs down and compare results over a longer term.

Where do you see $40 E5-2650v1? I want some.
If strictly using for XMR mining, L3 cache dictates number of threads.
L3 25mb is 12 threads , with E5-2660 , E5-2650 , E5-2670 , In bios , I only activate 6 physical cores , then disable the other unused cores.
Having more than 6 cores per CPU have no real benefit for XMR mining.
Got 8 x E5 v3 CPU package deal
They are all stepping 2
3 x E5-4655 v3
3 x E5-4610 v3
2 x E5-2666 v3
They were as below he has 10 at 49.99 thought there was a best offer., so etimated 40... but price still good..all others are much higher..

We All know the 2mb/thread cache requirement. What impact does the clock freq have on hash rate? I'm trying to see if the increased power and heat for the higher MHZ and the sweetspot of hashrate, wattage, cost. Aren't we all.
