Intel Xeon E5-2630 v3 Haswell-EP 2.4 GHz 8 x 256KB L2 Cache 20MB L3 Cache LGA 2011-3 85W BX80644E52630V3 Server Processor

Pros: Runs cool, mind you I put a Noctua NH-U9DXi4 cooler
Good on power consumption
Easily handles multiple virtual machines. I run between 3-6 mix of Win2012/10 and Linux variants
Converting video in Plex is fast when multi threading kicks in. About 14 min for a 1hour 1080i clip to a playable mp4 high quality clip for Ipad. Compared to 30-40 min on my old AMD Phenom II X4 965 Black.

Cons: More of caveat than a con. I think these have to be used in the right context. Don't expect raw power from these compared to higher clocked CPU. For single threaded use my older 3.4 Ghz quad core AMD Phenom out performed in terms of "perceived" performance. e.g. booting most VM's in KVM was faster or felt snappier.
At full bore cores will max out at 2.6 Ghz and only rarely will you see 3.2 from a few cores depending on workload. Lookup intel turbo boost. Maybe water cooling can help but temperature I think only plays a small role. So generally a higher clocked CPU will outperform single tasking operations.
Arch Linux is running great serving up to 6 VM's with loads of background services. However if I were to start over I'd go for a higher clocked 6 core Xeon for more punch with the day to day stuff.

Overall Review: As already mentioned in another review DD4 speed capped at 1866
If, like me, this is your first Xeon CPU you might be better served by something like a Intel Xeon E5-1650 v3 unless you really know you need 8 cores and this is your price limit.
Although a great CPU I think these ones excel in multi threaded environments and are primarily designed for multi socket. Which I guess should be obvious given the E5-2* designation which at the time I was searching I didn't realize.

Pros: Runs cool. Uses less power.

Cons: Cannot outperform my 7 year old Core2Quad Xtreme clocked at 4.1GHz for basic video editing in Premiere. I'm experiencing dropped frames at 1080P and 4K resolutions.

nBench floating point performance comes up about 30% slower than my Core2Quad.

Cinebench R15 single thread performance is similar to my old CPU/machine. Not the upgrade I expected.

Overall Review: I'd really thought that Moore's Law would apply to CPUs, expecting a very significant increase in performance over my 7 year old Core2Quad. That this new system with TWO Xeon CPUs stutters and drops more frames than the aging Core2Quad system that it is supposed to replace, really left me speechless. This CPU should leave the C2Q in the dust, video editing-wise.
My peers are editing this same footage on Macbook Pro's with none of the problems I am having. The footage cannot be that difficult to decode and play back if a laptop can do it. Certainly a dual Xeon should be more capable than a laptop. But the results contradict the expectations.
I've spent all month with tech support for the various system component, and reached a dead end, and also exceeded the RMA period, so I am stuck with the monthly payments for this behemoth, even though it is nearly useless for the intended purpose. Other system integrators use Xeons in their high end NLE workstations, so I don't understand why common NLE apps perform so poorly on Xeons. My mistake was to try and clone one of those high end workstations and DiY it myself instead of paying someone thirty grand to build it for me, where I have recourse if it doesn't perform well. Oh well, it's only a year's income in financing that I am on the hook for now. Live and learn.
