I have a relativly tight budget gaming PC, but still pretty good nontheless. I can run most games on atleast high or very high. Tried playing really graphic intense games like Metro and it ran smoothly. I played Shadow of Mordor aswell, it ran perfectly without any problems(great game aswell, a bit repetitive but great nontheless.)
Current games that i am playing are: Fallout 4, Battlefield 4, League of Legends and Civilization V.
