The problem I see is at least a couple of those games will need a dual core with hyperthreading, for four threads, in order to run well. Lowering resolution won't solve this problem.
Some games require a lot of videocard power. Lowering the resolution can help here. For instance, I doubt anyone would want to run Rise of the Tomb Raider at higher than 720p when using a GT 1030.
So it's not really a question of bottlenecking. Bottlenecking implies the CPU can handle the game, just not as fast as the videocard will allow. In your case, your Pentium dual core can't handle those CPU demanding games no matter how powerful a card you have.
You'd need to know what kind of motherboard you have to see if maybe a CPU upgrade to something like a...
