If I can run the game with a Core i3, 6gb of ram and a GTX 650ti, on high/normal settings and a relatively high resolution. At the best of times my frames are between 30 -50 and rarely dip below 30. Your system on paper should cope much better given yours is a quad core and mine is a dual. Although do remember the game is not so well optimised so it could not run any better than mine.
