The low voltage i5/i7 laptop chips might surprise you. Some CS6/CC actions can be interminably slow, but most - eg colorcorrecting, PS sharpening, NR etc are fine - at least in a non-professional/production environment. Wonder if the older nividia laptop graphics chips are inferior to the current ULV Haswell built in graphics (HD4400) - I have no experience with it, and was wondering if anyone has used these new chips for photo editing. Maximal, display port only, externally supported resolution, for the HD4400 is stated to be 2500x1000 (approx) - which equals the PA721. Not sure about real world use.
Still asking if there's any need for a small, second, SSD for photshop cache, if the primary SSD is huge (750GB) and is run at 50% capacity.
