Make sure you get a VR headset, like an Oculus or such. It will change your life as far as these types of games go. No screens can even remotely compare...
As far as games, if you want an arcade style then go with project cars 2 if you want something closer to real life, then get iRacing and join the PCA leagues. It's SUPER competitive in each skill level.
