Buying a gaming pc and might buy an xbox controller and wondering if you need anything extra to make the xbox controller work on the computer.
If you would like to use the wireless controllers then you would have to purchase the adapter for the PC.
A wireless controller can be used by purchasing a wireless receiver and plugging it into your USB port. Just install the software that will come with it, takes all of 2 seconds, then you sync the controller to the receiver, which will have the little button with the wireless symbol next to it, and you'll be ready to go.
I use a wireless controller on my PC, so I bought a receiver. If you go wireless, I would recommend ebay, I got mine for about $10.
