I have noticed that the PCBs of many HD 6850s have seatings for a second power connector but it is not installed. I was wondering if one can simply solder second connector on and if there is going to be any benefit. Same goes with the fourth phase on the card but I am not willing to attempt messing with that. BTW, I have a Sapphire HD 6850 (100315L) on the way for my secondary rig. Any modding suggestions are welcome.
