I am planning to buy a laptop. It has Nvidia Geforce GTX950M, 8Gb of RAM which is great for gaming. My only concern is it's processor which is Intel i5 5200u. I made research and it turns out this CPU is not really high performance. It has 2 cores and slow clock rate. Will it be a huge problem for me while playing games such as GTA V? I am not expecting ultra-high graphics but at least I want to play some new games.
