DDR-3 makes the decision even harder as it carries an extreme cost at the moment but do those dollars actually translate into extreme gaming performance? Technically speaking, in pure megabytes per second, it is fast, thanks to the attainable speeds 1500MHz double data rate and beyond which can be achieved, without too much effort. However, the big issue with DDR-3 memory right now is the fact that its latency is high, much higher comparatively to more finely tuned DDR-2.
What does this all really mean for the gamer, though? Are we going to be pushing an extra 1FPS? Maybe 10? It all remains to be seen.
