intel Core i5/i7 CPU preferably none of the M(obile) versions (= slow) and a dedicated nVidia GeForce GT(X) graphics card… min. 8 GB RAM (maybe w/ 1 slot free) and a SSD is recommendable. If you are working in bright surroundings (e.g. outdoor) do prefer a matte display preferably w/ a IPS display (= wide viewing angle, better colors).
