The i7 basically gives you a slightly higher clock speed and hyperthreading. Probably not worth it on a dollar per performance basis. > - can someone point out a GPU known to flawlessly work with DT and Debian > stable? This thread has some info: https://sourceforge.net/p/darktable/mailman/message/32046692/ It basically boils down to: AMD and nVidia cards both provide OpenCL support, but AFAIK Intel drivers don't yet have OpenCL support. Get at least 1GB video RAM, preferably 2GB. As for flawless: no, you still have to run proprietary drivers, which is a pretty major flaw, IMHO. I was vaguely looking at this stuff recently and it seems to boil down to how much power you're willing to burn. Have a look at the GFLOPS/W column: http://en.wikipedia.org/wiki/List_of_Nvidia_graphics_processing_units#GeForce_700_Series Seems to me it's pretty much constant. So you get twice the performance for twice the power dissipation. So, in the nVidia range, a GTX 750 or GTX 760 might be good options, with the 760 having roughtly twice the performance and twice the power use. I was considering something like this: http://www.cplonline.com.au/asus-gtx760-oc-2g-gtx760-dc2oc-2gd5.html Or you might consider getting a 750 Ti if you wanted to optimise performance per watt. Something like: http://www.cplonline.com.au/msi-geforce-gtx750ti-twin-frozr-n750ti-tf-2gd5oc.html > - is 8 GB RAM enough or it is worth additional effort to reach 16 GB? 8GB should be sufficient but I'd get 16GB, personally. I occasionally run darktable on my 5-year-old laptop with 4GB of RAM and, if I use wavelet-based modules like the Equalizer, darktable will gobble almost 100% of the RAM forcing everything else out into swap. > - I will buy one SSD and one "common" HD, do I have to take care of > something special related to photo-editing in > choosing the models? Nah, anything will work. Photography isn't particularly i/o intensive, unlike say video editing.
