i want to push my fps in "Fortnte battle royale" (i get upwards of 200 fps but thats uncapped and in a real game with 100 people it struggles to hold 120 fps) but im not sure what to upgrade can i just slap a new graphics card in and get instant results? and then gather a new cpu ram and motherboard or shold i go for my cpu first? i only really want 144 stable fps.
