Core i7900k + rtx2070s Fortnite FPS?

Can I achieve stable 240FPS with Core i7900K + RTX2070S on low settings? I want to buy a 240hz monitor, is my CPU and graphics card good enough for a 240Hz monitor? Play Fortnite Competitiv and therefore wants to switch from 144hz to 240 hz

You should be able to play smoothly even on high settings. And for low settings that is definitely enough.

You can't play with the setup on low setting because the PC is underwhelmed. You can easily play smoothly on ultra.

It all depends. Full HD gaming with high to very high settings shouldn't be a problem. WQHD is hard with 240 Hertz at high settings and you don't have to talk about 4K, since even a 2080Ti doesn't get very far with very high settings.

But I want to play on 240FPS because I will have a 240hz monitor

I need 240FPS because of 240hz monitor

1920x1080

So Full HD is enough.

Yes you can easily with high settings
