Don’t forget to Time Machine. You never know what 10.9.5 will bring when it comes and I have a feeling this is going to be a reoccurring theme with how Open CL is getting updated by Apple and how little communication takes place to Apple’s partners before the release.

The ram profile for AE 2014 is very large that I have seen in testing so far. Even 1 layer of 4K at 30 seconds is taking over 90GB of ram for ram preview at full resolution. At auto resolution its taking far less. Also the ram preview is caching far more to disk if the ram preview usage gets to close to your max ram. Then it will cache to disk and rebuffer. You will likely have to look at increasing your ram on these systems. Until then lower the resolution for ram preview and that should help.

I wasn’t referring to the spec differences of the CPU such as cores, GHz, cache and such. I was referring to the actual architecture of Xeon versus I7. What you mention beyond that are simply platform differences between desktop and workstation/server platforms. Both the Server ie Xeon platforms and the workstation ie socket 2011 platform have QPI. There is no difference there. The Server platform has a QPI bus between the 2 CPU’s for syncing data between then. Beyond that they both use the QPI instead of the front side bus. The Cache in the CPU’s is dependent on the cores. The more cores, the greater the cache since the cores need cache to run optimally and they share. A 6 Core CPU doesn’t require 25 Meg cache. However a 8 or 10 core will. The 12 core has 30 meg cache and Apple, HP, Dell, and all other system configurators use the same 12 core Xeons. Incase you didn’t know Apple uses the 1600 series V2 Xeons which are the same as the 2600 Xeons other than they don’t support more than 1 chip on a board. Other than that it’s the same Xeon.
ECC ram has zero bearing on performance or reliability with media applications. ECC is meant for server operations that have an operational time of 24/7 365. It has zero bearing on media applications so I am not sure why you bring it up. Yes the Server chips support more then 64GB of ram but most don’t need more than that. If the editor does then a Dual Xeon system whether from HP, Dell, or custom configurator all have the same ram options available. Once again T1’s have no advantage there. They are using the same core hardware. All are using the same Intel chips if their Xeons. All are using the same desktop or mobile chips if their those. Intel doesn’t ship special CPU’s to anyone.
As to performance, the higher clock speeds available for the workstation chips are outperforming the greater cores of the Xeon chips with GPU acceleration for most codecs. Once the system has the ideal cpu threads for decoding the data then GHz becomes far more important than extra cores or cache. You can reference benchmarks I posted here reflecting that has not changed for example with Adobe CC 2014.

You have generation loss if you render to most compression based codecs out which are not designated as lossless. If you render out the files uncompressed codecs/formats or lossless codecs then you normally wont have a generation loss. The lossless codec’s though come with a caveat. Some are listed as lossless but still have some quality loss which doesn’t often show till you render it more than once. Those are normally called visually lossless.

HP and Apple use those same processors. The CPU’s are the same whether you get them in a Apple, HP, Dell or other system configurator or e-tailer. The is nothing different to Xeons over I7 CPU’s that allow for any “any heavier lifting” than the I7 or workstation chips. The Xeons only have specific firmware for security and Server operations. Beyond that the CPU’s are the same and zero difference. You can also install those exact same Xeons in many X79 boards if you want. I personally run a 2697 V2 12 Core in an x79 board. That has even better performance than the equivalent Apple due to the hardware options available on the PC including NVidia cards which work better with Davinci currently. No amount of testing or benchmarks will show any performance or reliability advantage with Tier 1 oems versus other hardware.
I would not expect HP or Apple to know what you need or what works best with those applications either. Their support wont cover those applications and their functionality either. It ends at the hardware. There are other system configurators that do use standard hardware that can be upgraded with any standard hardware available online or at retail. Those configurators often know far better what hardware you need and support far more than just the hardware. Keep that in mind before you assume the Tier 1 oems are the only viable option.
BTW The Tier 1 oems purchase hardware from the same companies you find available in the channel/retail. They may have certain OEM done but the majority is industry wide hardware available in retail.

$2500 to $4000 puts you in the budget range for 2 platforms on PC that would handle the 4K media atleast at /12 resolution preview with those applications. The 4790K with 32GB of ram, 770GTX 4GB card, with a raid 0 media drive would be the solution in the $2500 range. Clocked at 4.5 to 4.7GHz this configuration can playback 4K full res with the GPU accelerated debayering. Adobe has that now but Davinci doesn’t yet.
The workstation X79 system with the 4930K, 32GB to 64GB of ram, SSD OS, 770GTX 4GB card and a raid 0 media drive would put you in the upper range of the budget listed. However with the Asus boards or Asrock Extreme 9, you have the ability to upgrade to a E5 V2 Xeon CPU such as the 10 or 12 Core without changing the board out. This configuration at 4.4GHz can easily playback 4K at full resolution preview and even 6K with the GPU accelerated debayer. It will also handle Davinci along with the other apps better than the Quad Core Desktop listed above.
The others are correct though regarding the nMPro. The budget needs to be higher to get the config required for the same performance with 4K media as what I listed above. That is the trade off for Mac and OSX.

Did you connect it via USB and install the utility to manage the converter? If not install the utility with the converter connected via USB. Turn the video processing off. Also check your settings.

12GB of ram is not enough to support the amount of threads you have with Multiprocessing enabled and leaving 4GB of ram for other applications. You really want 2GB of ram per CPU thread available in the system besides 4GB for the OS and other applications. 1.5GB per thread would really be as low as you want to set it to. I would suggest increasing your ram to atleast 16GB but ideally 32GB if you want to enable the multiprocessing and use all of the threads you CPU has. AE uses other processes besides the render engine/player such as Quicktime Server/Player that requires it’s own ram allocation as well. You want to make sure you have enough ram for those processes and the multiprocessing as well. That is why 32GB is really where you want to be for 8 CPU threads.

DNxHD can be formatted with Quicktime ie MOV or MXF ie OP1A as an example. The MXF DNxHD performs better on windows and is native to Adobe CC. That is what I would suggest using. Keep in mind though you can also download Cineform and convert the AVC media to that. Cineform is a better codec than DNxHD but requires you to install their software to have the option available in Media Encoder.
Matching Sequence settings can be done just by dropping in 1 of the media files to create the sequence. However the frame aspects are really the only part that matters when you select sequence settings. The Adobe player will still decode the media regardless of what you set the sequence settings to.
