The OCZ Enhanced leads use copper shielding (much like very expensive AC cords) to keep EMI and RF at bay, and for cards like the Geforce 6800 Ultra that needs every ounce of power it can get from the PSU, these cables can do much to increase overclocking stability, and prolong the life of your video card and HDDs. Also, while serious line conditioners and AC power cords can cost hundreds of dollars, you can pick up the OCZ Enhanced power leads for around $10 online, which makes the purchase pretty much a no-brainer. Highly recommended.
