TechPowerUp GPU-Z is a simple but practical utility to find out which graphics card is installed on your computer.

But much more than that, it gives you the full lowdown on its capabilities, status and whether it can handle the type of games or applications you¡re trying to push through it. The program is compatible with just about every brand of card there is and gives you data such as the name, brand, model, memory, bios version and DirectX driver among many other things. The other nice thing is that there's absolutely no installation required. An added bonus is that the program can take you directly to the TechPowerUp website which shows the percentage of users who use each brand and where in the world they can be found. Apparently, the program does have a slight bias towards NVIDIA and ATI cards but its very useful for diagnosing if you're suffering from overclocking.

This is a simple but handy tool for anyone wondering whether their graphics card is able to handle the latest programs and games.
