they didnt care, when they pulled sli from the 975 boards that had sli support from the company that made the ati SB on the 3200 chipset (i forgot the name of it) but when NV bought them they killed the sli license that they had and removed the drivers from the 975 before the core 2 came out, there was a huge push back to get it put back but NV didnt care and said that they could only use it with the old drivers
