Do you know what the HEDT reviews are missing? Actual proper parallel work flow testing. Very often I'll be rendering out a Cinema 4D scene and compiling a Unity app while working in Premier Pro. It's workflows like these where TR really shines, I'd love to see this represented in reviews, be interesting to see if AMD and Intel platforms handle it differently.
Hell, I was exporting a Premiere render last night and hopped onto rocket league for a couple if games while waiting, couldn't even tell in game that the render was happening.
Computerbase.de did some testing like this.
