I can't tell from the picture, is it scratched on the edge or pitted/chipped. I've had CPU and VPU cores with chipping on the side. Not suprisingly, most of these are ones with tight fitting or very heavy/awkward heatsinks installed. But your right, this calls for my favorite word for a situation such as this, "bummer." But, on the bright side, I never noticed any difference in cooling performance between perfect chips and their slightly damaged siblings.
