Get the 9700np. Performs better out of the box and can be o/ced later. But if you don't want to spend the money, go with the 9500pro. 9600pro should be a last choice of the three IMHO. Eventhough its a good performer, it doesn't do so well against the 9500pro, let alone the 9700np.
To sum it up, if you have the money and don't mind paying for the 9700np, go for that one. The FIC 9700np at newegg.com was a good one, but I think its out of stock.
