Is there any way to get around this if a game doesn't support the use of SLI? I just bought a GTX 560 Ti, and I was thinking if I should get a 750w XFX PSU to support 2 560 cards, but I'm not so sure now I have heard about compatibility issues with some games.

I understand that the 560 will kill most games, but all I was wondering was whether there were other compatibility issues with games that don't like to run with 2 cards. I was looking at an SLI compatible list and a lot of older games weren't on there which made me think that there were software constrictions that were incompatible with running two cards.
