Totally Bob. So many other bottlenecks for 8K. What I read from the article is that if I was a post house with grunty computers and doing lots of r3d footage, I might pop a second RTX Titan card in the box instead of a Red Rocket to save $3000+ and get the same result.
I’m currently specing for a new computer that will be capable of 8k even though I’m not expecting to need it just yet. So it’s on my radar and this info does help to inform me about the slots, cooling & power supply I will need.
