computer for photo editing
Post this in computer forum; they'll set you straight. From PC world you want an I7 cpu with atleast 8gb of ram. For macs you still want 8+gb of ram, but i dont know what cpu's they support... Some software packages offer acceleration via video-card driver, but usually thy dont work with radeon and nvidia cards, nvidia uses cuda while radeon uses opencl so all depends what the app supports. Get the card that matches. This will help with batch processing of 100s files, but i doubt you will notice difference between high end d consumer grade video card working on 1 file at a time. Video card should have atleast 1gb of ram.
