You need at least a 4590k not to bottleneck it very hard. I5 2400 performs like an high clocked i3 6/7th generation. And since you can't even OC it , you're in a though spot.
Will depend on the game but you should get an enjoyable experience but I recommend capping your fps to stop huge fps variances. A stronger CPU would help but definitely worth trying what you have now first, you might be happy with it.
