after getting the fury x for xmas I bought my self a nice 4k monitor. I was quite happy with the solid 60 fps at medium settings. last month I found a fury nitro on amazon new for 254.00 plus a 30 dollar mail in. so I did it, and now I'm kicking myself. I score 18306 in firestrike which is fine. My problem is I just cant seem top get BF1 to work properly, I cannot play anything above low settings. I get no more than 30 -40 fps in an empty server. I have tried multiple settings in crimson , I have tried multiple driver versions same results. If i disable crossfire, I'm back to normal , I swapped cards to see if maybe the nitro was defective but it works just fine in single card config. what am I missing? both card are reading x16 in the bus, cpu-z says my memory is at 2400. I am using an Ivy-bridge i7 4820k, clocked at 4.1. please any and all help is appreciated. and if all else fails I will be selling a nitro for cheap cheap in the eastern US. *** I now have a EVGA 1300w psu so no power issues either.
