Hi I'm buying a computer from cyberpower and I can't seem to find a cut and dry answer to my problem. Speed of thr RAM I'm going with an i5-760. What ram is fast enough for this processor without having it over clocked. I just don't want ram that's so fast I'll never use it to it's full potential. I plan on doing DDR3 4GB. Just don't know if like 1800MgH is 2 fast or not. It is a gaming computer.
