I have just recently built my first gaming pc, (http://pcpartpicker.com/b/R0H) but the graphics card doesn't seem to perform as I expected. I was playing dayz epoch and it struggled to get up to 60 fps when most settings were on normal and anti-aliasing disabled. Is this the cards power, or is something wrong? I am fairly certain the drivers (bios and gpu) are all up to date because I have checked them many times. I thought the gtx 770 was supposed to run games like this on max settings with no problem? Can someone suggest something? (I am running windows 8)
