Looking to upgrade my graphics this Black Friday specifically for playing DayZ. Right now I'm running a HD 7770. Typically when I upgrade I go by this site to see what the best bang for my buck would be. I'm looking in the 150-200 range so my top 2 choices are either an R9 285/380 or GeForce GTX 960. The only thing I've heard is that Nvidia typically runs DayZ better than AMD. Any truth behind that?
