The question is simple. I will be over overclocking, please keep that in mind. There isn't really any price difference so basically what I want to know is which card will overclock better and which cooler will keep the GPU the coolest. Below are links if you need them. Evidence to back up your claims is always welcome. Thank you all in advance!
