I've heard a lot about different DRAM. What actual difference will that make? Will I get faster processing power, internet connectivity, what will happen? I don't want *cue squeaky voice* "This system has xxxx speed, making it far superior to this system, with xxxy speed" *uncue*. What real-world benefits do RAM types, and faster RAM speeds have? I don't understand much about this sort of thing (RAM-wise, I'm good with other techy stuff), so if you could explain to me in easy terms, it would be appreciated. Thanks in advance.
