ECS GTX 460 Black
 

While the 885Mhz on the cores is less than what I have been able to squeeze out of other cards by about 15Mhz, the memory speeds just flew on up past what I have been able to gain on other cards. This equates to a 120Mhz jump on the cores and 153Mhz on the memory or a roughly 16% increase in clock speeds between the two settings. The question you have to ask then is did I see a 16% jump in performance? Not quite at the lower resolutions where other factors contribute to performance but at 2560 x 1600 - yes I did. That makes it all worth the effort.
