Thanks for detailed suggestions.
BTW, I started using DT after a video from you, thank you for having done it.

The i7 basically gives you a slightly higher clock speed and hyperthreading.
Probably not worth it on a dollar per
performance basis.

This thread has some info:

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:

Or you might consider getting a 750 Ti if you wanted to optimise performance
per watt. Something like:

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.

Nah, anything will work. Photography isn't particularly i/o intensive, unlike
say video editing.
