It's not really worth it. the 600 pounds price tag is too steep and it's mainly designed for extreme overclockers in mind, not casual overclockers, but extreme overclockers, if you plan on watercooling it and testing it to the max, then yeah, it's for you, but if you just want to install it in, and do nothing with it, it's not worth it, you'd be better off with a cheaper evga model or the cheaper asus model, also, the LN2 mode basically defrosts the memory chips, because a common problem is the memory chips freezing , that's why you see overclockers with blowtorches and that, to melt the ice that's formed on the chips, so ln2 mode basically defrosts the chips without your help
