The advantages of multi-core processors start showing their best in contemporary games. Looks like three but not two cores has become the optimal choice for the growing number of gaming engines. At least Phenom II X3 outperforms its rivals from Core 2 Duo E7000 series in three tests out of five. Nevertheless, we can also consider Core 2 Duo E8400 to be another good option for games in this particular price range. Compared with the E7000 series, it uses faster bus and has a larger L2 cache. However, AMD solutions are still a little cheaper, so there is more than one choice available to you from the price-to-performance prospective under this particular type of load.
