a 3070 should be MORE then enough. Especially with a 13th gen processor. I only have an 11th gen processor and a 3060 and I'm 100% confident I will be able to run it at 1440p at max settings with decent FPS. I might upgrade my system if I see others able to run really high fps (120+) without the issues the game used to have at high fps, but I don't think it's going to be needed at all considering even the recommended requirements are several generations behind.
