Question about Samsung 990 Pro

Hello, since I have an ASUS WS X299 Sage/10G motherboard, and it does not have PCIe 4.0, doubling the bandwidth per lane compared to PCIe 3.0, so the samsung 990 can't go over 2400M/s which is not good for video editing, instead of 7400m/s, I would have to change the motherboard, and the processor to exploit its potential, it's frustrating because every time you buy good hardware, you have to change the rest, and you go in circles.
