don't know what are you guys talking about, but I know, that zotac I have, has the best performance, rather palit superjetstreams I have earlier.
it has higher core frequency and memory frequency, and I don't know  what should a man do with a card, to brake PCB?! once installed I will never touch it again, it is working and working.
personally, I prefer to take ASUS STRIX, but by the time I have money for it, the price for Asus goes too high - more then $850. Zotac I took for $730 and Palits less then $700.. so the choice is obvious for me here
