g4 scott said that the geforce 3 was out on the mac before the pc, it was actually on the pc months before apple got it. i think apple users wanted more options and that's when nvidia stepped in, nvidia doesn't have dual chips is really not a matter for them, you could m,ake them but nvidia makes the chips, not the boards, dual chips also causes pc problems with multiple devices of the same kind, such that the only real dual chip was an old voodoo card that worked as two boards together. it had it's issues, now osx could use dual chips for an nvidia gpu, just need somebody to make the board. ati was like apple, you don't see dell making apple computers, you don't see abit or asus making ati cards, only ati made them, seeing nvidia get such a jump in the market now ati is letting manufactuars use the radeon chips for their boards in hopes of the same effect. ms does alot with direct x and open gl has been more developed on a pc, i think osx will work all that out soon and the driver issue will go away. it just needs to be developed more and then the speed will follow. do remember where nvidia's trust lies, 95% of their market is with pc users so i wouldn't expect they'd piss them off by releasing for apple first, i know we'd all love that but realistically it's not lookin good. we'll just see in time i guess, best case i would think it comes out on both at the same time.
