1gb superclocked 560ti vs. 2gb nonsuperclocked 560ti

Really! Why buy a pre-clocked card, get the 2gb version and just overclock it yourself, the OC that are given by the manus are so so so easy to pass with a literal click of a button

If it's just OCed, then I agree not to bother, if it comes with a better cooler also then it's something to consider.
