I upgraded my graphics card i had a R9 270x 2 gig and upgraded to AMD Radeon R9 390x by msi. My frame rates increased by maybe 5 frames not sure why. the rest of my system is AMD FX-9590 Vishera, 16 gigs of corsair vengeance ram, gigabyte motherboard 990FXA-UD3, and a 750 watt Corsair power supply. Any help is appreciated!!
