We learned that R600 can be overclocked to 850MHz easily on its default cooler and with this special water-cooled edition, we can expect even higher clocks. Interestingly, we heard that any core clock increase on the R600 will scale the performance by much which is why ATi is trying hard to boost the core frequency higher. R600 real performance remains a mystery till now but we believe ATi still have some chance if they can deliver the products out on time.
