Thanks Steven for the time and effort putting together this article. You have put into words what many of us have probably done as a mental exercise.. cruising through eBay looking at older, cheaper technology trying to figure out if it still has any use in our life.. or just the fun of putting together that illusive "insanely fast system for hardly any money" system that won't make the wife mad once the bills arrive.. "Look honey, this would have cost me a bajillion dollars a few years ago.."
I agree with your basic premise for this build.. for SPECIFIC tasks using SPECIFIC software, this system has real value. But I do have a couple of problems with what you wrote..
First, yes the CPUs are dirt cheap but.. a compatible NEW motherboard isn't. I couldn't find the Asrock EP2C602 online at $280. It is out of stock at Newegg (Google cache page shows it was out of stock before your article was published.. and $310 when in stock), not available at NCIXUS.com, Microcenter.com or Frys.com. It is available at Amazon.com but through a 3rd party for $600 ($310 when Amazon did have it in stock). Searching for an alternative motherboard with the X79 didn't produce much better and negates a big chunk of your argument for getting a Xeon E5-2670 in the first place. None were found at NCIXUS.com or Microcenter.com, Frys.com were all "Available for In-Store", and only two "open box" X79s were available at Newegg.com. Amazon.com had plenty but most were $500 or more with the EVGA X79 132-SE-E77-KR being the cheapest ($356.48 shipped). Of the only two X79 motherboards offered NEW, each had only two each available.
It would have been nice if you mentioned where you got this motherboard for $280, WHEN you got it, and where more (or something similar) can be bought NOW.
Secondly, you may have overstated how well Premiere works with a many core/thread CPU. An article from PugetSystems from August, 2015 (
https://www.pugetsystems.com/labs/articles/Adobe-Premiere-Pro-CC-Multi-Core-Performance-698/) stated..
""if you search for "how many cores does Premiere use" you will find forum thread after forum thread saying "as many as you can give it!". That is somewhat true - Windows reported all the CPU cores as being under 90+% load - but our testing showed that Premiere Pro was not able to effectively use all of those cores.. at lower core counts Premiere Pro ranges from being decent to excellent in terms of utilizing each CPU core. The problem is that at a certain point (as low as only 4-5 cores) the parallel efficiency drops off dramatically.. generating previews was actually more efficient at utilizing higher core counts than encoding was. We still saw a drop off after anywhere from 4 to 7 cores"
It seems to full utilize a many core/thread CPU, specific and usually costly software is needed. This expense isn't factored into the calculations on whether this really is a "cheap/inexpensive" build or not.
Again, thanks for the thought provoking article. Unfortunately perhaps a bit more complicated in realistically putting together this system as cheaply as it first appears and utilizing it to it's fullest potential.
