3DMark 2003 run at 1600x1200, 3DMark 2006 used defaults. As you can see, more CPU muscle doesn't really help. FarCry2 benching is a mess, the results vary quite a lot, the more often you do it the slower it gets. But anyway, the results are still quite close. The L3 cache surely helps with games, but you may compensate that disadvantage with higher clock speeds.
