The 2011 Pin system is probably the best choice for using Premiere Pro. It is not the cheapest option, but has advantages over a normal Skylake system and is not as expensive as a Dual Xeon. The 2011 pin (or Broadwell-E as it is also called) can take more RAM and has more internal expansion capability than the Skylake. the Skylake will work very well, but the 2011 Pin is more "future proof" in that you can expand the system more easily. The name 2011 Pin refers to how many pins are on the processor, not the year in which it was released!
The 2011 pin systems main advantages over the "Skylake" processors are:
♦ The motherboard can use more RAM so it is easy to install up to 128GB RAM which the 64 bit Adobe applications will use.
♦ The motherboard is more expandable in terms of the number of extra PCIe cards you can install. In a standard Skylake system you could have a graphic card, Blackmagic Intensity Pro 4K, and maybe one other card happily working. In the 2011 PIN there is room for these plus a RAID card, and possible extra FireWire sockets, as well as other interface card (maybe two graphic cards for Premiere Pro CC). This means the 2011 pin is more expandable.
♦ More hard drive connections. The 2011 pin boards have 10 SATA connections internally where as the Skylake only has 6.
♦ The USB3 chipset used in this motherboard has had some issues with some external drives, Blackmagic devices and some RAID boxes. We recommend adding in another USB3 controller (as listed in the configuration). The Skylake motherboard has a good USB3 controller built-in.
