And on top of that, if your graphics card is just the 2080 then I would say upgrade the graphics card and not the cpu. Depending on your current cpu, you GPU may be the issue. I would say before going to a 700-900 dollar cpu, get a 2080 super or 2080 ti or something like that. It may be more expensive, but large frame drops tend to be from either lag or GPU throttling. Also check your WiFi/Ethernet because rubber banding is usually from lag and fortnite’s servers can sometimes drop large packets of info when on the final parts of a match. Also remember is that doesn’t work, get lots of rgb cuz it makes your computer faster.
