FurMark

your video card supports OpenGL 2.0, FurMark is an app for Windows that can test its performance using tests based on quality generating algorithms. The algorithms used by FurMark are optimized to heat up the GPU (graphics processing unit) and test its stability and resistance to extreme situations. FurMark allows you to select the resolution of the test, if it will do it based on time or by frame and if it will use MSAA (Multisample anti-aliasing). Some video card models compatible with FurMark are: NVIDIA Geforce 5,6,7,8 and later; ATI Radeon 9600 or later; and the S3 Graphics Chrome 400 Series or later.
