A system is used to test a 3D image processing capability of a video card. The system includes a 3D model engine module, a 3D model module, a test parameter module, and a check module. The 3D model module is capable of building a 3D model engine. The test parameter module is capable of setting test parameters. The check module is capable of checking a test result. The 3D model is processed by the video card within the test parameters and a running environment which is set by the 3D model engine under the test parameters, and the check module checks if the video card processes the 3D model properly.
