Computer Science: Testing your graphics card

Probably the most demanding task a home computer preforms is rendering 3D games. In some case the GPU (Graphics Processing Unit) can outperform the CPU on the motherboard.

Here is a list of Link to some Graphics Card Benchmark programs.

Benchmark test using DirectX11
Unigine Heaven DX11 Benchmark
Futuremark 3DMark 11

Benchmark test using DirectX10
Futuremark 3D Vantage

Benchmark test for DirectX9
(Dude! If you are still using DirectX9 for your gaming needs go back to playing Farmville or Freecell on your computer)
Futuremark 3DMark06

Benchmark Stress Test
(This test has temperature data as well)
3DGeeks' FurMark

Physics: Dics Brakes and Work done by Friction

In the following video we see the kinetic energy of a rotating tire (or moving car) converted into heat. As the brake is applied, the friction in the systems does work to slow the wheel down. The energy from the work done by friction manifest itself as heat. The disc brake become hot enough to glow brightly. Here are some sample videos.
