On the economic advantages of redshift or other gpu renderers. My current workstations are Mac Pro 3.1s which are left over from the company I shut down in 2009 (bootcamped into Windows). Essentially worthless from a CPU standpoint. Putting a single $1000 titan gpu into one of them makes it more efficient at rendering than any modern 16-core $8,000 workstation running any CPU ray tracer. Putting 2 titans in them is like having my old 162-core blade server renderfarm without the $5000/month electric bill. Not to mention all the IT overhead and license costs.
I have never seen a single piece of software (in concert with the astonishing graphics hardware that is now so cheap and still getting cheaper) have such a cost-reducing impact. Plus they are fanatically hard workers and great communicators.
