The Phenom has slightly better performance than the Athlon, but they are both very good choices. If price matters to you, getting the cheaper of the two won't set you back that far in performance.

It's better to go with the Phenom. More bang for gaming

Thank you for the help I just didn't know which one to pick considering there is literally no price difference between the two

How is that, y2adre? They are so familiar to each other, it wouldn't matter.

either get the Athlon II or upgrade to Phenom II 9xx series.
the 840 is an Athlon II in disguise. It does not have L3 cache like the rest of the Phenom II's. It means the two processors are exactly the same, but one is clocked .1 ghz higher. .1 ghz makes very little difference.
