As far as I can see you shouldn't have any problems running Titanfall when it is released. I would however change a few parts of your build. I would recommend getting 2x4GB Ram as opposed to 1x8GB, this way you can take advantage of multiple RAM slots (faster). I would also recommend seriously considering a good power supply. The PSU is one component where it is generally worth it to pay more. I would reccomend any of Corsair's power supplies, but mostly just don't buy an off brand PSU.
