Hi guys, Thanks for your replies.
Turns out that different people are buying my brother computer components for his birthday, so hes now going to have a new intel i9 9900k processer on a ROG maximus xi hero wife motherboard, but the graphics card is staying the same (
Nividia GeForce GTX 1070 ).
So am I correct from reading your comments above that this should be more than ok to run Train Simulator 2019?
