Effects of GPU frequency on 3DMark 06 Scores (9800GTX Single)

Overclocking your GPU will affect the rest of your system components in various ways. We look at how a single 9800GTX card is affected with synthetic benchmarking using 3DMark06.

Overview

Ever wondered how GPU frequency changes would impact 3DMark06 scores? We check it out using a single 9800GTX graphics card.

The intention is to overclock our friendly Intel CPU to 4.0GHz and then run 3DMark06 three times for every subsequent increase in the GPU’s frequency (Core, Memory and Shader).
