911 medic the person that is writing the topic you refer to couldnt be more new to Overclocking. He is obviously refering to a Rivatuner/Drivers Overclock and not a Bios overclock. Thats Mainly why i always prefer and recommend a Bios Overclock and not a Software Overclock.
Now why would a person spend all his time doing software Overclocks i dont know but like i said i dont think his best field is Overclocking.
jakup hard to say since i didnt bench the card prior to oveclocking the shaders from 1250 to 1500. If anyone else wants to OC the shaders make sure you bench it first
