After some discussion, i realized that this kind of database could be used for mutch many goals such as:

1. Collecting drivers performances/functionality related to machine configuration (to be clear: a more-reliable  Driver Guide-like rating panel);

2. Generating specific (aka per-user) RSS-like feeds for drivers update;

3. Collecting/comparing more detailed and reliable machine performances and relative stats (such as techPowerUp! Overclocking Database's Automated Test Suite);

4. Help manufacturers to improve their products compatibility with other components;

5. <anything else>

Let me know what you think.
