Kicking off the availability of PCMark 8 through Steam is a 25 percent discount. For a "limited time," you can snag PCMark 8 Professional Edition for $37.49 rather than its normal selling price of $49.95. In addition, keys purchased from Steam are interchangeable with the standalone version, so you needn't worry about that.
The paid version comes with the following:
- Includes all five benchmarks plus battery life tests
- Benchmark with Adobe and Microsoft applications
- Test your SSD or HDD with the Storage test
- Measure the battery life of your tablet or notebook
- Run individual workloads to fine-tune your system
- Get in-depth hardware monitoring graphs
- Automatically save your results online
Alternately, a free version is available that includes the Home, Creative and Work benchmarks, along with a free online account to manage your results.
