but what objectively makes that more expensive? the most expensive chips are actually low clock, more cores eg. 2699. so why they bubble on a couple high clock ones?
I would assume that the high clocked ones would be less commonly used in servers and more in workstation environments.

Gets a look in for servers for things like high frequency trading but more importantly per core licensed DB's, think Oracle where a 3.5+ghz 4-core is cost efficient, often with 64gb ram or more per core. (So 2 x e-2637 v4 and 512gb or 768gb ram), same holds true for say 8-core parts also, and 2x8 also keeps you at or under the magic 16cores for things like Microsoft licensing.

It also depends on whether there is a focus on multi-threaded performance or a focus on single-threaded performance. If it is a focus on single-threaded performance and requirements than an 8core or less would be used. If it's multi-threaded performance as a requirement than a 10 core or higher with a lower clock speed would suffice. For your example of HFT/Algorithims that would be high single threaded performance with some emphasis on multi-threaded performance (for multiple instances).

I'm looking to pick up 2 of these, mainly for VMs and a Plex media server. Seems to be quite a few of them available on eBay. Are these the current bang-for-buck CPU?

I just upgraded two 2670 v1's ($200 for the pair) to 2680 v2's ($350 for the pair). The performance increase in my specific situation (plex, file server, VMs) is not worth the premium. Others may have different needs and different opinions.

I would recommend spending the cash differential on more memory instead - critical for a file server if caching mechanical hard drive writes.

(If you would like my 2670 v1's, just send me a message.)

what about energy efficency ? Idle powerconsumption ?

25% performance increase and you pay $150 more, of course the performance won't worth the premium. However highlights for v2 is on power consumption... You should save couple bucks on the power bill every month.

Why do you think that a 115 W-rated E5-2670 draws more power than a 115 W-rated E5-2680 v2?

I think 2680 v2 is def more cost effective than 2690 v2 or 2696 v2 at this point. it's too bad we don't have anything else left for 2011 v2....

4 year leases will be seeing the last 2680,90 v2 etc hit the market 2018 and early 2019, with that the last ddr3.

This is pretty accurate... Recently picked up 2650L's, 2660's and 2680's. Definitely worth it, from a performance and power perspective. Replaced some 2670 V1's and 2643 V1's. Less heat too.

Ivy Bridge CPU's bring some performance benefits for VMware, so, that alone helps workloads versus the V1's if you are running many VM's on one machine...
