I'm currently looking into buying a controller for my pc, and preferably I'm going to pick a PS3 controller. I know there is software out, but I don't know which one to choose. I'm currently running windows 7 and Vista on my other computer, I would like them both t be able to use the PS3 controller. But which programs/method should I use or is there a guide up? I tried looking but I'm not sure. I also heard that some methods can harm your usb ports/devices. So which is the safest method that is guaranteed to work? Thanks.
