OCC has published a new review of the Asus EN8800GT TOP

As a factory overclocked card, the expectation was that the increase in core clock and memory speeds would not be that significant. Overclocked cards usually have little performance headroom left to increase the clock speeds to gain additional performance. The final speeds I attained were 60MHz above stock on the GPU core and 44MHz on the memory. Neither were really significant, but high enough to increase the performance of the Asus 8800GT. This allowed the card to perform much better than a stock clocked 8800GT. The performance increase in benchmarks was sometimes not evident in games until the higher resolutions were run.
