well i know you can unlock the regular 6800 to 16 pipes and 6 shaders but i have heard of people doing it and it artifacts with most cards . is there a certain 6800 that it works best for like xfx or eVGA. and tigerdirect says the 6800 xfx core is 352mhz 700mhz memory and on newegg there is no core listing for xfx model 6800 is that a typo or is it really 352mhz? and all the other 6800s core is only 325mhz and 700mhz memory
