I am looking for a decent video card and have narrowed it down to these two. I was planning to buy the ASUS model because they have good cooling, but I can't decide between the 760 or 770. I would mainly use it for playing games like DayZ, Counter Strike, and Rust. All I really want is a solid 50-60 fps when playing these games. Would the 760 do the job or should I invest in a 770?
