The best gaming CPU is the one that can handle the load when the game is working hard. All games differs in how much CPU power they need depending on what happens in the game. If the game is in a actions scene then physics, fights etc makes the processor work much harder, process more memory and there is where you need capacity from the CPU.Originally Posted by gallag
By using a slow video card or higher resolution it is possible to filter away fps numbers in the higher areas (the video card will cut the high fps values) because those aren't important for game play anyway (the game will slow down on the lower areas). The older Phenom was good if you did this filtering but it was rather hard to filter values in right areas. If the video card is to slow that will bottleneck the game all the time and then you don't see the lower fps areas.
Phenom II has make it easier to see the lower areas where it is strong, the margin is wider because it is good (better compared to Phenom) on areas where there is little action, maybe only one core need's to work and most data needed can be handled by the big L2 cache on Core 2 processors.
Making the filter more narrow (higher resolution and/or slower video card) will increase the lead from Phenom II if the test shows this behavior, of course it depends on how the game works. Single threaded games that doesn't use much data will probably get best performance for a high clocked C2D.
Testing average fps has the effect of counting frames from different areas in the game
