Would the 2600 be a limiting factor when using Photoshop and doing very light video editing? I'm not a gamer, do no 3d stuff, don't use aperture/lightroom. Is there a point in me going for the 8800? I mean would there be any noticeable difference at all for my purposes? When I say very light video editing, I mean very light. Really just adding watermarks and cutting clips into shorter segments.
