GPU-Z is a simple but handy tool for anyone wondering whether their graphics card is able to handle the latest programs and games. GPU-Z is very useful for diagnosing if you're suffering from overclocking.

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.

The other nice thing about GPU-Z that there's absolutely no installation required and is therefore completely portable.
