Upgrade to AMD Ryzen Threadripper 1950X 16 Core Processor

Yes I upgraded my desktop that I primarily use for processing my astrophotos and did a little bit of PixInsight benchmark and here are the results.

UPDATE

While doing a lot of performance optimization to my rig, I noticed some slow performance and wasn’t really happy with it so I decided to do a clean install once again.  We’ll this time the rig is more stable and the recent results for the PixInsight benchmark proved my findings.  With a gain of 3,713 points of the total performance score with a little bit of a tweak and installing the system on the M2 drive proved it’s worth effort.
