While upping our Core i7 920 to 4.0 GHz represents a big boost in terms of overall clock rate, this doesn't immediately translate into huge performance increases. With this much CPU power at your disposal, other aspects of your system configuration quickly become bottlenecks. Our GPU-limited 3DMark Vantage test doesn't show huge gains, as our 1.5 GB equipped QuadroFX card became the bottleneck, which shows what kind of power we're dealing with on the CPU level. However, in the specific CPU benchmark, we see sizable performance increases with each overclocked level.
