X700 is pretty overclockable, x800 fairly overclockable, i'd say normal amount, and depending upon your number of fans. They can both go about 5-10% beyond stock speeds.
The x850, well that gets interesting. In order to oc it well, you need good case fans, at least 2 120mm ones, along with a fairly unobstructed air flow path (ie rounded floppy/eide cables). Then, make sure there's room for exhaust. I can oc mine 15% beyond stock speeds, although that's with the leaf blower fan on max.
