I bought a 2070 2 weeks ago and the card came with dead memory so i sent it back to amazon and bought a rx 5700 xt and it works fine but the fps keep droping. im 14 and dont really know anything about these cards but i can barely play i have a i9 9900kf 8gb of ram do they have anything to do with it i have to use my old 1050 ti from my old tower and it lags and looks horrible.
