I7 9700 + 4070ti anyone?

Yes, exactly - this is my point as well. Unless you’re pushing 4K resolution, MSFS is largely a CPU bound title that scales directly with processor performance. I would take the time to upgrade the CPU and motherboard, then save the GPU for your next upgrade step. If staying with Intel 12 or 13th gen, you can use your existing DDR4 RAM to save money.
