The list of current benchmarks is a good gauge to test the performance of CPU's in different aspects, and I think that it is more than enough in that area. Practically it doesn't matter what type of games are included as long as there is several games in the benchmark that gauges the performance of CPU's in different environments - my point is that nobody buys multiple CPU's to play different games at the highest performance level.
I would suggest more practical comparisons - boot-up times, time to open common apps like MS Office, performance when playing HD and SD movies, and overall power consumption of the system. And if possible to have these practical benchmarks of older systems up to 2-years back for comparison. This is important because those are the systems that are primarily due for upgrade.
I've been a regular reader of Tom's hardware way back when it was more known among the techies as "sysdoc.pair.com", and I've made decisions in the past (more recently a few months ago) to upgrade a PC component due to compelling benchmark results, only to find out that it has no impact on the performance of my PC in terms of user experience. As an example, I recently upgraded from Phenom II X3 720 to Phenom II X4 970 - on reviews, you can see significant difference in performance, on actual usage I can see no difference on regular apps - browsing, playing movies, MS Office, and others. This is the same thing if you increase the memory of your PC - from 4GB to 8GB, you cannot notice performance difference on regular usage.
These practical benchmarks can also be applied on other component upgrades such as video cards and hard disks. In my personal experience of being a PC enthusiast for more than 20 years, the upgrades that are really noticeable are the the hard disk upgrades and the cpu cooler upgrades. An upgrade from 5400 rpm HDD to 7200 rpm provides instant performance boost that is noticeable, and an upgrade from HDD to SSD provides the best performance boost in almost all areas of regular computing. An upgrade to a good after-market CPU cooler does not give you the performance boost without overclocking, but significantly lower cpu operating temperature that definitely improves reliability of the system.
