My IBM ThinkPad T42 has been with me for more than 4 years. I changed its main board, hard drive, CPU fan during these years. It is still okay for normal daily office use. But cannot use it to play 3D games at all. The display adaptor ~ ATI Radeon 7500 mobile edition cannot play most of the 3D games nowadays.

GPU-Z ~ a free utility designed to give you all information about your video card and GPU. It provides displays adapter, GPU and display information. It also provides displays overclock, default clocks and 3D clocks. I use it to trace my ATI HD 4870 GPU temp and fan speed. It has log to file function. Therefore, you can trace these during game play.
