and right now i have SLI GTX 560 and I'm a little confused on what all the other slots are to be honest, based on the description. Help would be nice, I would like to use the SLI and whatever cheapy card I can get just for PhysX for whatever games utilize it, like metro 2033.
Any recommendations on what I can/could use? if anything on the market? Or am I outta luck using an older card on this board?
