So I just pulled the trigger on two of them as well. I guess I won't be buying a Vega based GPU this year.

Interested to hear your choice of chassis, fans, heatsinks etc to get it as silent as possible to have it inside an appartment :)
They will be placed in a Supermicro 846 chassis with a few silent fans. I will also use supermicro passive heatsinks with a custom fan attached. I expect some noise when I use all 24 cores, but for most regular tasks it will probably be near silent.

Waiting for the E5-2690 V2 to drop down in price or even the E5-2697 V2 to come down further in price and maybe the E5-2687W V2. I presume that within a year they should at least come down further by at least 25-30% if not more. The E5-1680 V2 might come down in price but I heard it was primarily used in Mac Pro's and wasn't that common.
Concerning the fact that you will get about two E5-2690 v2 for the price of one E5-1680 v2, you should really only go the E5-1680 v2 route if you want to overclock it.

I was actually planning on going the route of overclocking the E5-1680 V2 on a X79 motherboard but not at the current prices they sell for. Eventually the prices on V2 processors are going to come down to V1 levels and I'm sure the E5-1680 V2 will also come down (the question is just how much).
The E5-1680 v2 is way too rare to ever get cheap, I suppose.

I looked for 1680 v2's and they are pretty rare at a good price. I decided to go with a E5-2667 V2. Not overclockable, but it is a tiny bit faster than the 1680 V2 stock.
Intel Xeon E5-1680 v2 - CM8063501589600
vs
Intel Xeon E5-2667 v2 - CM8063501287304

Motherboards are going to be the issue in the future. Good X79 boards might as well be made of gold. You can still get a few boards new from Supermicro and ASRockRack for V1/V2 but they are not cheap either. The X9SRA goes for about $270

About these mainboards: I bought a Asrock Rack EPC602D8A some months ago for my E5-1680 v2 because it had some overclocking options. And indeed you can change the CPU multiplier and voltages in its BIOS. The big issue was that I couldn't get the CPU to ignore its 130W TDP limit. There are BIOS options for short and long duration power limits, just like in any other X79 board, but they don't do anything. So under light loads I could run this Xeon at 4.2 GHz (all-core multiplier of 42), but as soon as something more was going on, it downclocked to 3.7 GHz. I monitored the TDP with HWMonitor and hwinfo64, it never got any higher than 132 W. The same issue occured with an i7-4820K in this board, it could never exceed its TDP.

As soon as I switched to an Asus P9X79 Pro, this issue was gone.

what would the benchmark be like relative to e5-2686 v1 and e5-2686 v3?

I just bought a 2011 v3 MB and 1x e5-2686 v3 cpu and 32GB DDR4 ECC ram.

Wondering if i should upgrade my old 2011 box (2x e5-2686 v1, 128gb ram) with these two cpu or just save the money toward another e5-2686 v3 and 16-32GB of additional DDR4 ECC?

I am leaning toward the 2nd option.. what everyone thinks?

I think he probably meant the e5-2687W (I think W was supposed to stand for workstation?)

Can't find any reference to the 2696v2 on Intel ARK. Is this an engineering sample?

Well as far as I can see there is no 2686 V1 processor. The 2686 V3/V4 do exist however.
I meant dual e5-2670v1. So is it worth spending also $650 to upgrade that system or should I wait a little more for the v2 cpu to drop even more?

I am building a dual cpu 2011v3 system right now... got one e5-2686v3 cpu so far with 32gb ram . Thinking I should put the 650$ to buy 2nd e5-2686v3 cpu rather than buy the two v2 cpu right now...

what does evryone think? Will v2 cpu come down some more in near future?

They have been dropping pretty steadily from what I have seen. By default the E5-2683 V3 is only 2.5ghz turbo on > 6 cores. I think the E5-2670V1 can turbo to 3Ghz on all 8 cores. Does the better IPC and couple more cores make up for the 500Mhz difference? I don't know. Passmark is higher for 2 E5-2670 vs 1 E5-2683 V3 with similar single core scores.

Personally for my workload, I wanted a good blend of clock speed and cores so the 8-core E5-2667 v2 fit the bill.

Yes it will I've already mentioned that even in this topic and on previous posts.
If v2 cpu price is going to drop some more, then i would rather wait. E5-2686 v3 (and I think all the other v3 and v4) doesn't look like it will really ever drop in the near future, unless someone tells me otherwise. So i guess i will put that $650 toward another e5-2686 v3 cpu....

I'm hoping to pick up some 10 or 12 core E5 v2's early next year to replace my 2670v1's.
