Hall I have a budget of 300euro for a graphics card. With which I can play fortnite with 240 fps in 1080p. Now the problem is that I have a ryzen 3 2200G. Which graphics card is suitable?
The processor will bottlenecken
No matter what you do, that's not possible.
300 euro is about NOTHING for your project.
Chewed an Office & Multimedia CPU out of greed & you want to buy a gaming GPU now? Courageously brave.
But will not work or clear. You will have more power, but not 100% full because your CPU is the bottleneck. If you need CPU & GPU new.
