besides the gtx260,275, 280 and 285, what other nvidia cards have a power saving mode. my old 8800gts didnt, my 9400 doesnt, what others ones do. I checked out a gts250 with nibitor but it said it didnt recognized the bios. I like my gtx260 and all but its overkill for physx. I have edited the bios to be less of a power hog in idle mode but I think I might down grade. If I do downgrade I would prefer a card with bios triggered power saving mode.
