Which one will give me the best performance for video and audio editing? They are both the same price on Newegg, and the 4gb looks tempting but will I truly utilize it, or would I be better served with less of a faster ram? The interweb is full of people knocking the 640 anandtech seems to favor the 650 more, but no mention was made of how the amount of ram affects the 640. I'm also not entirely certain as to what other performance benefits the 650 has apart from a faster ram.
