Seeing as their are several different designs from several different companies, I was wondering if I could get a couple of comments on the overclocking capabilities of these cards (specifically which one is the best for overclocking, without buying a water cooler). If you have any personal experience with the cards, or can point me to a site/thread that has something along these lines, I would appreciate it. Also, does the full PCB that EVGA has contribute anything to the offset of the core frequencies when you're overclocking (does it make it easier to overclock, or allow you to overclock higher)?
