Hot on the heels of its older brother - the GD65, comes the P55-CD53. To cite the major differences, this board feels pretty spaced-out since it has one tiny heatsink as opposed to the dual-piped heat-sinks on the GD6S. The RAM slots are packed closely. The CD53 bears a single PCl Express slot, and thus isn't meant for a SLI/ CrossFire setup. The board's build of her wise is quite similar to the GD65 and is satisfactory. The auto overclocking and base clock tweaking buttons are still present.
