Yes, it will be slower, because I am fairly sure the card will be rendering everything the right way up and then flipping it, and doing that with 3D could prove a pain.
It makes a lot more sense to do it properly the first place, so you can use different PCs/drivers/cards...
no, won't make any difference to speed as long as its in hardware whic for most decent cards it is.... it just changes its addressing scheme (eg, it starts sscanning at the bottom instead of the top of the screen)
