- Geekbench: Rapid CPU Benchmark
- 3DMark (Trial): Tests GPU and CPU back to back with their TimeSpy test. Free if you use the trial (which you should).
- Prime95: Extremely taxing on the CPU, much more so than any real world use case. Use for testing stability, especially on overclocks.
- 3DMark (Trial): Tests GPU and CPU back to back with their TimeSpy test. Free if you use the trial (which you should).
- Furmark: Not much to say other than it cooks your GPU. There's no "score" in the end like Heaven.
- Unigine Heaven: Can be used as a benchmark but I wouldn't as scores are very difficult to compare. This is due to the various amounts of settings you can choose from, I'd select the "Extreme" preset and move on.
- OCCT: Get the personal edition. It can stress test anything but I've found it to be mainly worthwhile for the ram. Go to stability test > memory > do 80% or higher on the memory scale and leave it. Can spit errors within 10 seconds but to be thorough leave it on for a couple hours at 100% memory.
