I bought a Sapphire r9 390 x a few weeks ago, and so far it has been a great card and handled all I wanted it to. But when I had finally saved up enough money to buy some of the newer games, like fallout 4, I noticed around a 15-20 fps lower benchmark than was recorded on the same card with other computers. I was wondering if anyone could help with this problem. Hardware: intel i7 5820k, Corsair dominator 16gb ddr4, Samsung 850 evo SSD, Hyper212 evo cpu cooler, and of course 8gb Sapphire r9 390x. Thanks to anyone who can help.
