Ditto. total gamechanger. Redshift is literally the only thing that kept me from closing up shop. I had priced out new multicore render nodes, and licenses for VRay and Arnold, as well as testing Arion, Octane and more obscure options, and the numbers just didn't make sense. I was going to just not be able to continue doing the type of remote work my clients expect on the schedules they need, and make enough money for it to be worth doing.
For example, I'm just putting 2 new render machines online - they're refurb Dell workstations that cost $450 each, with an additional 16GB RAM, ($190 each), an auxiliary drive bay power supply ($25!) and 2 GTX 780s ($850/pair). So each render node's hardware was about $1500, the Redshift license is $500, and I get much better performance from each node than I see from brand-new $10K 20-core CPU render boxes.
