I understand your point of view.
I didin’t buy these hardware for MSFS only, but for other games too. For example in RDR2, now I can everything maxed out on 60 FPS with rarely drops under 40 fps. On 1080 TI at these same CPU and ram, I wasn’t able to play in this game on MSAA 8x and many other ultra settings and FPS many times dropped under 30 FPS.
I will thinking about higher resolution gaming, but first I must to buy a monitor which can be able to play in 1440p or 4K.
