I want someone to explain to the best of their ability just how important is the frequency, capacity, and CL is to performance. Obviously You're going to notice a difference between 1333MHz and 2400MHz, but is a jump from 1600MHz to 1866MHz, or 1600MHz to 2133MHz even noticeable? I would also like to know, whats going to give me better performance, 1600MHz CL9 or 1866 CL10? Would going after something kind of rare like 1333MHz CL6 or CL7 be worth it? Thanks.
