Oh dear did you just call a 7970 Ghz Edition card a p.o.s (piece of sh**)? you're obviously looking for trouble. Also you will not be getting 1.3Ghz on the core of a 670 or a 680 unless you were the luckiest guy on earth' date=' not even with max voltage, you can't overclock those chips that much . [/quote']Doing it since last year may, see my videos chump. 2 other friends of mine with a GTX670 have done it as well but they dont make videos and upload to youtube. We buy at www.overclockers.co.uk and have been getting good chips over the years. That is one if the main importances as well, know where to buy good hardware.
