Connecting an Xbox 360 controller to your PC is pretty simple as you just need to pick up the little dongle that Microsoft sells. But what if you want to use the PlayStation 3 controller on your PC? Well, here's your answer.
MotionInJoy just got Microsoft certification for signing drivers so now, they've released drivers
for both 32 and 64-bit for Windows and used in conjunction with a Bluetooth add-on for your PC, you can experience using a PS3 controller on your computer yourself. I just tested it myself on my 64-bit Windows 7 machine and it worked out great.
So, install the dirvers, follow the instructions, and you're good to go.
