If you used Match sequence settings for the Media, try starting another sequence with Custom mode for the editing mode. Then set your editing frame resolution. Leave the Preview resolution set to 1080 and the Iframe codec. See if it will output then. I never got a chance to test that with the 4K card. Another option would be to try and switch the preview codec to Blackmagic and see if it will then.

Premiere will not scale down from the sequence frame size when using an I/O card. It will with the video card. As of right now I don’t know of any work around for this other than using the video card or go into the Blackmagic processing options and have it scale down in processing.

Yes that means the drive speed is not keeping up with the rest of the system and the CPU’s are waiting on the disk. The lan testing shows the latency of data is lowering the CPU load to the point Hyperthreading stops.

The amount of ram has an effect on the amount of frames cached and thereby export time. Once there is enough ram for the maximum codec caching then no the performance would not change nor the threading. CPU’s moderate ram so there is a direct correlation to CPU threading and ram allocation.
Yes core parking does have an effect on how much codecs multithread and I have tested it here. Feel free to test it yourself. H264 threads fine if it’s not using Quicktime. If it is then the threading is poor.

The reason greater than 16GB of ram is important is Adobe’s caching models for codecs change based on available ram. What is also a factor is how much open ram is available for the CUDA buffers in system ram. This will decide how many frames are cached and sent to the GPU ram at one time. The more threads you have the greater amount of ram you want to manage this otherwise you lose allot of the power of the Dual Xeon. This does not just have an effect in AE because you assign ram per thread. You just have more control there because of that.
Hyperthreading is a moderated function. The OS will not use it or do whats called core parking when it feels Hyperthreading is not needed or counter productive. The ACPI in the bios also effects this. Some boards currently are to aggressive to turn that off and this shows far more on Dual Xeons because they often run with far less load than single CPU workstations. If you turn the Core Parking off in the registry then that will stop the OS control on this.
DPX has far greater disk throughput requirement than AVCHD or H264 and also ram buffering. This means the data per frame is significantly higher and your network packeting will slow the entire encoding process down due to the encode and decode process. I can verify DPX multithreads fine with encoding from Red Media on local drives. This is something specific to the current limits of your config. We and other have done significant testing on major changes in Mpeg 2 encoding completely based on the amount of ram available. The encoding performance will increase by 50% when you reach a certain point on ram available and the caching model changes. Adobe has Optimized Mpeg 4 codecs with regards to ram quite abit since CS5 but the others use far more.

I would not dismiss Premiere or more accurately the Adobe suite in Post so quickly anymore. There is quite an exodus from both FCP and Avid to Adobe at this point and FCP users find Premiere very easy to pickup. I would try both and see what works best for your workflow since both have their advantages. I have quite a few clients who use both Premiere and Avid and I can promise you many Avid users also use Vegas because of the advantages Vegas has over Avid especially with Audio ie surround sound mixing.

Ok you may need to Re-install the Adobe suite then. I have never seen that greyed out. Make sure you uninstall the Blackmagic before you do.

Using a single 1GBE network connection for work storage is really not helping. I would suggest going local or 10GBE Ethernet. A single SSD 960GB drive local would handle allot of workflows. The Media your transcoding will also decide the performance. If it’s Quicktime then the performance on the Dual Xeon will be far less than others since Quicktime threads poor on Windows and is 32bit. The system wont hyper thread when the cpu load is that low. That is the OS and bios ACPI that will decide that. There is a way to turn that off in the registry though.

16GB of ram is really low to feed 32 threads especially since CUDA uses so much ram because of the way it works. I would highly suggest you get that up to atleast 32GB when you are able.
BTW another option is to use Cineform instead of AVCI. The transcode times with Cineform are really low compared to standard transcoding. Trial is here:

What player do you have set in the preview settings? Set it to the Adobe Player and see if the option lights up.
