After 5 years of using an E class CPU I have given up on the software developers and will probably switch back down to a Quad-Core CPU for the next refresh.
The main selling points of the E class CPU's I now class as largely irrelevant due to the speed of the boost on the Skylake Class CPU's.
SLI/Crossfire-X, it does not work properly, 32GB RAM? Do not need it.
My next rig I think will be quad-core, cpu, single card with 16GB of high-speed ram and NVMe disk.
All my video encoding/processing is now done on my Ipad Pro or my macbook pro. where-as in 2011 this was just not practical.
We are at the stage now where you can really over-kill the rigs and your only real solace is in the synthetic benchmarks to prove that its all still there and working.
