If these 8 series Amd cards launch at 1.2Ghz then these will be some seriously fast gpu's. Also if these speeds are correct, does this mean tsmc's 28nm process is much more refined? and will they have some decent overclocking headroom, like maybe 1.4ghz?

With this new competition and hopefully better drivers coming, i think i will hold off on buying a 780. I really don't like the way Nvidia's prices are going.
