hey everyone. im getting a new build and at the heart of it will be a ASRock Z77 Extreme 4 and I5 3570K. Im going to be overclocking the CPU as far as it can go. My question is what memory should i get? is there a particular speed i should be going for? is it worth getting faster memory because of my overclocking? the only thing is it has to come from pccasegear.com and keep in my black and red theme. i do quite like the look of gskill sniper but want the best memory for my build and overclocking. only going to be using 8GB as my buid is strictly for gaming. or should i get more?
