My computer is finally acting up to the point where I feel justified in buying a new one. Putting together a build, which I will submit for your approval of course, but is there any reason not to buy faster memory if the cost is about the same? I realize Intel only really supports up to 1600 (I'm going to buy an i5-4670k processor), but that's sort of a technicality. The higher speeds probably won't show any appreciable benefit either, but if they are the same price, is there a reason not to? I don't plan to overclock necessarily, but want to be open to the possibility, hence the k processor. Will the memory speed matter for that?
