It really depends on the graphics card. The 2060 should be able to run it fine. Remember , these games are designed to run on consoles like ps4. If you got it maxed out though , with the 2080 and i9, you will be able to run it at max graphics at 60+ fps without any issue at all.
That depends on the requirements for the game. Every game has its own system requirements. We would need to wait for the game to be officially released to confirm that information.
