For those of you that don't know Tom's hardware has an updated cpu hierarchy chart for both AMD and Intel cpu's. If you're looking at upgrading your cpu this chart should give you a good indication on the performance jump (or not) you may get when upgrading. Hit the link to check it out.

Fans of our Best Gaming CPUs for the Money column will recognize the hierarchy chart as a side-by-side comparison tool designed to help you pick an appropriate processing upgrade. It groups CPUs with roughly similar gaming performance into tiers. The top tier contains the highest-performing CPUs available and gaming performance decreases as you descend.
This hierarchy was originally based on the average performance each CPU achieved in our test suite. We have since incorporated new game data into our criteria, but it should be known that any specific title will likely perform differently depending on its unique programming. Some games, for example, will be severely graphics subsystem-limited, while others may react positively to more CPU cores, larger amounts of on-die cache or even a specific architecture. We don't have access to every CPU on the market, so some of the placements are based on the results similar models deliver. Indeed, this hierarchy chart is useful as a general guideline, but certainly not as a one-size-fits-all CPU comparison resource. For that, we recommend you check out our CPU Performance Charts.
