Hey all, my MSI Twin Frozr 560Ti coms pre overclocked but I was wondering if it's worth trying to get any more juice out of it, or should I just leave it how it is? if I can overclock it more should I just use the MSI Afterburner tool to do it? and what happens if I overclock too far? i've overclocked CPU's many times, but I havent overclocked a Graphics Card before so any hints and tips would be hugely appreciated, thank you for the help
