I am building my first gaming PC and I am trying to use it to play all of the games I like to play, like Battlefield 3 and eventually Battlefield 4, along with arma 3 and minecraft, etc. The thing is, I want to play them on 1080 ultra. I heard the evga gtx 770 2gb gfx card is a card I would need to play Battlefield 4 on 1080 ultra with good fps. What is the lowest Intel CPU I could use without bottle necking the performance of the gfx card. I was thinking that I would need a 4th gen i7, but I am not sure if a 4th gen i5 could do good too. Thanks
