Good PhysX card?

Been looking around for a PyshX card. Not sure if I want to do it but it seems as though I would need a GTX 465. These cards have to SLi connector. The bridge that I have has three rows of two connectors. So naturally the lowest end card that has two connectors is the 465.

Are there any games that you play or are going to get that use PhysX? If not, don't worry about it until that point. It was my understanding that you don't need it connected with an SLI connnector. Any Nvidia card from 8800's up will work, the faster the better though. You just go into the Nvidia control panel and tell it which card to use for that.

Well, show's how much I know, lol. Might pick up another 450. They are under $120 right now on Newegg.

Thanks y'all
