the I5 is overclocked to 3.8 ghz and I got a new heatsink. The games I'm noticing drops in are Total War: Shogun 2, Team Fortress 2(which makes no sense), Battlefield 4, and Assassins Creed IV. I run them all at 1920x1080, before on my 570 I would get about 45 fps on Shogun at Medium High settings. I used the same settings but only get 35-40 fps, I updated the bios on my evga classified p55 200 and everything but I'm not running things as I should.
