I'm using an Acer Aspire 4830T with Core I3-2370 2.40 GHz integrated graphics, 4 GB ram. I've never had any problems due to the hardware that I know of. I am comfortable with the performance, although I know that folks with more muscular systems do less waiting. I would like to answer questions about openCL support and amount of RAM that gets dedicated to graphics usage, but someone would have to tell me how to do this. I do not know for sure if this is Haswell or a different processor. If I have an image with a complex stack, with denoising and chromatic aberration included, then I see "working..." for several seconds on the image every time anything happens. I am OK with that. I do wish that exporting images to JPG happened faster. This really does take some time - probably 15 - 30 seconds for a complex stack and full resolution (crop sensor Canon) export, but I've never timed it. Again, if you have any suggestions for some kind of benchmarking, I would be happy to do it and send you the results. All I have for RAM consumption at the moment is the observation from running top that I had about 1.4 GB of RAM in use with my email client and browser and a few terminal windows open, and when I started DT, this went up to about 2.2GB. I realize that is not terribly informative, but seems to show that I am not starving for RAM with 4GB, and perhaps gives some indication of an upper limit on what the integrated graphics are struggling along with. I'm running Mint 13 LTS, with Cinnamon and the current DT in the repositories is 1.2.2. According to System Information, I'm running I915 graphics, so not Haswell? With "Mesa DRI Intel Sandybridge Mobile" OpenGL Renderer.
