I think I am discluding the Corsair Value Select from my choice here.
It's cas latency is 3, and though said before that differencs between 2 and 3 are minimal, I think for the amount of money I'd be spending more for the OCZ or GeIL it's worth it.
EDIT: Nubius, that's what I meant. Overclocking aside, 'mega expensive ram' holds little advantage over less expensive value ram. Of course maybe the extremely high end ram does, but you get my point right?
