Trying to decide between the i7-4770k vs the i7-4820k for a photo-editing rig. They are roughly the same price (about $40 more for the 4820 + MoBo). I am interested in the benefits of the quad channel memory of the 4820 vs the dual channel memory of the 4770. Would I ever notice this in real world applications? I am pushing some pretty huge files through Photoshop and Lightroom (and occasionally InDesign, Illustrator, and Edge).
