Benchmarking software is easily available online, and most of it is free. Here is a list of the prominent benchmarking tools — followed by the simple method for using any of them.
MSI Kombustor
This benchmarking tool usually comes bundled with MSI Afterburner itself — the natural first choice if you followed the hands-on module.
It is also available to download separately from the same official MSI page.

Unigine Heaven
Another very useful benchmarking tool, Unigine’s Heaven is preferred by many gamers for testing the effects of overclocking. Its long looping flight over a fantasy world is a classic stability workout for any card.

Unigine Valley
Another great offering from the Unigine stable. Like Heaven, Valley comes loaded with all the necessary qualities — but with a more scenic backdrop for your benchmarking: a vast, forested mountain valley.

Futuremark 3DMark Basic
Just like the two tools above, Futuremark’s 3DMark Basic edition is a benchmarker that will meet all your needs. Its scores are the lingua franca of the enthusiast world — ideal for comparing before-and-after results.

GPU-Z
One of the most reliable and trusted names for checking an overclock, GPU-Z is a very useful tool for checking your GPU’s health — every sensor, clock and specification of your card in one compact readout.

Using any of the many benchmarking tools available is very easy once you’ve downloaded and installed one. First, run the software and select the ‘Benchmark’ option.
The tool will push your GPU to its limit and measure how much pressure it comes under. Then activate your overclock and run the program again.
Compare the score you got without the overclock to the score you achieved with it — the difference is the improvement in your GPU’s performance.
