Just got my 2nd HIS 6950 to go with my first for xfire, will be the first time ive ever done it but was wondering is it worth flashing both of the cards to 6970's or leave them as 6950's and OC them a little (never OC'd any of my gfx cards always left them at stock), or 3rd option is flash them to 6970's and OC them.
