The first step towards using a PC like a game console is to sort out the hardware. A standard gaming computer is extremely powerful yet also large, loud and expensive. It’s simply overkill for playing most games, particularly console ports. Here are the modest specifications I recommend.
Intel Core 2 Duo or better.
Radeon HD 7770 / NVIDIA GT 650 Ti or better.
4GB of RAM.
500GB Hard Drive
Chique
