Mid-Range Overclocking - Synthetics
At lower settings there's a noticeable bump, but at higher resolutions and with eye candy enabled, once again we see the video card bottlenecks and prevents much of a performance increase.
Here we have a bit of an anomaly. Some SPECviewperf scores increase, but a few decrease with the overclock.
The total PC Mark score gain with the overclock is somewhat limited - probably by the hard drive test, which the overclock doesn't help - but the remainder of the scores scale nicely with the increased clock speeds.
