Viewperf is a benchmark from Spec.org that was created by IBM. The utility provides a complete analysis of system performance when executing OpenGL applications. The program is comprised of 9 scenes and benchmarks system performance in each scene. As a heads up, some of the scenes aren’t very CPU dependant and, since this is a graphical benchmark, focus more on the video card.
Thus, the video card will probably be a main limiting factor in the benchmarks.

The results are all around the place. The Athlon FX-62 leads the pack for AMD’s solutions while the Core 2 Extreme QX6700 is unsuccessful in gaining first place. The best it reaches is third.
