Hi Matt, thank you to Puget for doing these tests on photoshop. Though useful, the set of tests is mostly automated so they can be easily reproduced between different system setups. It's only half the story for photoshop performance and doesn't show the whole picture. I come from a concept/matte artist background and work in photoshop 90% of the time. My saved files can reach over 2GB in PSB format. The benchmarks I would like to see is how interactive and responsive the software is with user control. For example when you're airbrushing, is there any lag in the brushmarks? After converting a layer into a smart object, I tend to do warping and puppet warp so I can come back and tweak them. Is it smooth or it takes a moment between moving the warp handles around? What about transform operations on a layer (Ctrl-T command) do the corners move smoothly when pulling with a mouse or tablet? How about spot healing brush, finger painting and blending colors, etc

Another feature I use a lot is just panning around by pressing spacebar. I've noticed the refresh rate got worse and worse with each PS CC updates. Is that CPU or GPU dependent?

For me it's all about direct interaction. I don't want any lags in the performance. I don't really reduce noise or blur photos on a daily basis. A good benchmark test I do on systems for responsiveness is to create a 30,000 x 30,000 pixels canvas use a 3000 px airbrush with a reduce spacing of 5%. Then make brush stroke on that canvas and observe the lag. It's just to push the system to the limit. I know these tests are harder to replicate exactly between different systems but they are more indicative of photoshop performance than an image resize will ever be. What GPU/CPUs/Memory combo would reduce that lag. Maybe you could come up with a set of tests like that.
