So what would I consider Atomic about the Sapphire HD 3870 Atomic Edition? Well, as for it packing an Atomic punch in performance, no. With the heatsink being a single slot cooling solution, it does it have the efficiency to cool better than the larger two slot solution? Yes. What would I consider the best value out of the whole package would have to be the bundle of software, HDMI cable and Cold Cathodes.
