3DMark is one of the best benchmark suites for evaluating system performance, especially GPU performance. It's a great tool, and while the free version is sufficient for most people, the paid version offers a wealth of options and additional tests. You can unlock it now on Steam for only $4.49.

The Steam listing does not overtly indicate that the paid version is 3DMark Advanced Edition, but it is. It normally sells for $29.99, but occasionally goes on sale. This is one of those times, and it is well worth the asking price, if for no other reason than that you can skip the demo when running the benchmarks. [There are other perks as well, such as access to Time Spy Extreme, a 4K version of the DirectX 12 benchmark. The paid edition also includes several other benchmarks that are not accessible in the Basic Edition (free version), such as the real-time ray tracing benchmarks Port Royal, Wild Life, Wild Life Extreme, Fire Strike Extreme, Fire Strike Ultra, and stress tests. Several other benchmarks that are not accessible are also unlocked.

You will also have access to several functional tests.

The Advanced Edition allows you to configure custom benchmark settings, install tests individually, and save results offline.

Those who want to go all out can get 3DMark Advanced Edition as a bundle with PCMark 10 (another widely used and cited benchmark suite) and VRMark for $8.98 (down from $79.97). Both are very good deals and worth adding to your catalog of benchmarking tools.
