PureOverclock has a review of a well named card from Gainward, the BLISS 6800 GS GLH.  If the memory overclock they managed to achieve is typical of this card, then you can have a lot of fun tweaking it to an inch of it’s life.
‘Gainward’s BLISS 6800 GS GLH is no reference board. Sure, the core headroom is still up to the gods, but the memory headroom will destroy the competition. I managed to clock the memory to 1480 MHz at its peak. Just try and do that on any other 6800 GS with 2.0ns memory, it just won’t happen’
