I'm currently using a i7 8700k, rtx 2070 and a asrock extreme 4 mobo with 16gb 3200mhz g.skill ram. I'm looking to up grade these parts over the next few months. As I can't afford the do it in one go, what order shall I replace the new parts? I'm maybe looking to get i7 12700k cpu and a rtx 4070 card and not sure on the mobo yet.
