No I listed above as to why you can set it to zero and still continue work. I did not assume that AE is the only application launched and even stated why and how it works. What I said was Premiere will be effected by far more than just the CPU processing and the system has to have all of the resources available for Premiere to function in Realtime. I never set the CPU to anything beyond 0 left and most of my clients work on other projects while AE is rendering. I wasn’t the one assuming here. I have tested this far more than most and am fully aware how it works.

Get the 4790K which can clock over 4.5GHz very easy. Also get a z97 board which can have Thunderbolt as an add on card if Asus. That is far better for AE and motion graphics than that Xeon CPU. Also 16GB of ram is what you need at a minimum. An SSD drive for the OS would be ideal and look for the Crucial M550 or Samsung Pro drives for that. If you plan to use any other Adobe application besides AE then get an Nvidia card such as the 760GTX 4GB or 770GTX 4GB. Don’t rely on simulated Open CL benchmarks for graphics cards. Those benchmarks don’t reflect performance in Adobe or most GPU acceleration application accept for Vegas.

Multiprocessing only takes longer when your ram preview is for very short segments and you have allot of CPU threads such as a dual Xeon. If you only have 4 to 12 threads then multiprocessing will definitely speed ram preview up most of the time unless you don’t have enough ram for the system.

Premiere is a realtime application versus AE and AME which are not. If you launch Premiere while rendering via AME, AME will take far longer because Premiere will grab the CPU resources instead of leaving them for AE. AE is also a background render application and not realtime so it will just take far longer to Render out. However Premiere will not have as many resources available including ram and disk access and would be effected since it’s a realtime application due to the realtime playback.
If you want the most performance with ram preview and render queue in AE then set the CPU left for other applications to 0. If you need to use Premiere then while it’s render queuing then that can always be changed if the performance is not enough to playback realtime. However setting CPU’s to sit idle when you only have 4 to 12 threads is not a good idea since AE requires the most processing and ram for it’s work and is the largest time sync.

The OS moderates threads based on interrupt and priority. If another process needs to take cpu time it will interrupt based on priority. I have been setting these to zero for years and never has an issue with it since AE uses CPU’s as background resource priority.

Yes set the CPU reserved for other applications to 0. Definitely get more ram before an SSD if you want to utilize all of the threads in AE. The Ram preview is faster on a system with more cores if you use the multiprocessing for ram preview as well. Don’t turn that off for ram preview unless you have to for something.

16GB of ram is not enough for 8 Cores. You really need 2GB of ram per core/thread and atleast 4 to 8GB left for other programs. I would suggest moving to 32GB of ram atleast. I suggest setting the memory saved for other applications to 4GB. Set the ram per background CPU to 1.5GB and use what cores you can. Smaller comps should not exceed that most of the time. No this does not effect Media Encoder. AE 2014 has a very large ram profile so get as much ram as you can.

This is older blog post but still gives an idea of why Cineform is a better option for grading and such. Also Pro res and DNxHD are DCT codecs which means block based compression. Cineform is Wavelet based which eliminates block based artifacts often shown with blocked based compression.

Mac Drive allows you to read and write to HFS+ drives on windows. That is all you need for dealing with OSX formatted drives.
