SPECviewperf 8.0.1	Source: SPEC.org

SPECviewperf® is a portable OpenGL performance benchmark program written in C. It was developed by IBM. Later updates and significant contributions were made by SGI, Digital (Compaq, HP), 3Dlabs (Creative Labs) and other SPECopcSM project group members. SPECviewperf provides a vast amount of flexibility in benchmarking OpenGL performance. The SPECopcSM project group made data changes to viewsets running under SPECviewperf 8.0.1 to discourage optimizations that benefit the benchmark, but might not improve real-world application performance. Since the SPECviewperf source and binaries have been upgraded to support some of these changes, no comparisons should be made between past results and current results for viewsets running under SPECviewperf 8.0.1.

Higher numbers equate to better performance.

Unreal Tournament 2003	Source: Epic

Unreal Tournament 2003 is the sequel to 1999's multiple 'Game of the Year' award winner. It uses the very latest Unreal Engine technology - where graphics, sound and game play are taken beyond the bleeding edge. Unreal Tournament 2003 employs the use of Vertex as well as Pixel Shaders and it's recommended that you use a DirectX 8 videocard to get the most out of the game.
