Answer #1
eliminate the 8600GT
diff memory amounts make the other 2 about equal with the 9600GSO/512mb being the best

Answer #2
If you want to game: none of them, GS cards where not made for gaming, they are good if you want to view some hd content or aero, but gaming: nope, you nead a GT card, but that 8600GT card isn’t what you would call gaming material either.
If you want to game: save up some more money, cause those 3 cards are a waste of money if you want to game.
Answer #3
9600GSO, its a rebadged 8800gs.
