The Golden Sample is clocked with a 450 MHz core which is 4 MHz faster than one of the overclocking sweet spots (18 x 27 - 40 = 446). Now, as our last 7800 GT review showed, the good thing about the 7800 series is that we see good performance boosts when they are overclocked. There were some instances of a 10 fps increase in some benchmarks with reasonable overclocks.
