www.casejunkiez.com have today posted a review of the new Crystal Orb GPU cooler from Thermaltake. Heres a snippet:

    Due to the heatsink being nickel plated it's hard to say wether the whole heatsink is copper or not and the only noticeable mould lines were around the holes where the fan screws in to the base, but weighing in at almost 100 grams fully assembled makes you wonder. Did I mention the nickel plating? The base of this heatsink is almost mirror smooth and the overall finish of the heatsink shows nothing but quality cosntruction techniques were used.
