It will work provided two things...
A) Its NV40 (Which all 6800GS AGP based models are, so were good there)
B) The bitmasked pipes arent already physically damaged in some way.
Its not that hard, takes about two minutes if your moving your hand at a crawl speed, and if the pipes are damaged and produce artifacting, you can uninstall RivaTuner and revert the card back to default. If the artifacting continues, just RMA and claim it came like that :twisted:
(I realize its not ethical, but were trying to accomplish something here)
